1. Introduction

Compiling this documentation executes a series of ScriptBasic programs and gets both the source code and the result into the final documentation. The reason for this is to have regression test for each new version of ScriptBasic more or less documented.

Some regression test can not be performed from this documentation compilation. In such case the source file is still included into this documentation but the program is not executed. These are CGI programs, console IO testing programs or some programs that require more interactivity than just stdin input and stdout output.

This documentation was created using

'scriba' is not recognized as an internal or external command, operable program or batch file.

2. Command Line Tests

[Contents]

2.1. testnt.bas

This test some functions of the module NT.

Example testnt.bas :

import nt.bas

print nt::RegRead("HKLM\\SOFTWARE\\SCRIPTBASIC\\CONFIG"),"\n" print nt::RegRead("HKLM\\SOFTWARE\\SCRIPTBASIC\\DWORD"),"\n" print nt::RegRead("HKLM\\SOFTWARE\\SCRIPTBASIC\\BIN"),"\n"

' nt::RegDel "HKLM\\SOFTWARE\\SCRIPTBASIC\\BIN" nt::RegWrite "HKLM\\SOFTWARE\\SCRIPTBASIC\\BIN1","kakukk" nt::RegWrite "HKLM\\SOFTWARE\\SCRIPTBASIC\\DWORD1",614

nt::RegWrite "HKLM\\SOFTWARE\\SCRIPTBASIC\\" , "default value"

' nt::RegWrite "HKLM\\SOFTWARE\\SCRIPTBASIC\\SUB\\DWORD1",614

Result executing testnt.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

The result printed should be the full path to the configuration file of the actual installation and undef twice.

After executing this script check the Windows NT registry to see that the sample program has written some information into it.

[Contents]

2.2. reftest.bas

This program generated access violation until v1.0b26. This was because ScriptBasic handled variable references to other variables in an extremely simple manner.

Example reftest.bas :

sub test(a)
 undef q
 print a
end sub
q[1] = 1
test q[1]
print q

Result executing reftest.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

[Contents]

2.3. const.bas

This program test the difference local (module local) and global constants.

Example const.bas :

module TEST
a = "VARIABLE"
Global Const a = "a "
Const b = "b "

sub TestSub const c = "c " print " values in TestSub=",a,b,c,"\n" var a print "a in sub=",a,"\n" end sub

print "values in the module=",a,b,c,"\n" print "values called from within the module:\n" TestSub var a print "a in module=",a,"\n" end module print "values outside the module=",a,b,c,"\n" print "values called from outside the module:\n" TEST::TestSub var a print "a in global=",a,"\n"

Result executing const.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

[Contents]

2.13. testcall.bas

This program tests the function call features of ScriptBasic. This tests rather the syntax analyzer capabilities and less the run-time. The function call syntax is rather free and is implemented by a special syntax analysis function in the interpreter. It is allowed to call a function without the keyword Call is the function is already defined, but is needed if the function/sub is not defined yet (before the actual function/sub definition).

Calling a function can be with and without arguments, and the arguments can be enclosed between parentheses but it is not a must unless the function is called inside and expression. Using parenthesis can be confusing when the first argument is enclosed between parentheses but the argument list is not. For this case a special algorithm is applied that counts the opening and closing parentheses on the line following the function call. This is tested in this program.

Example testcall.bas :

Call MySub(1,2,3)
Call MySub 2,3,4
Call MySub(3),4,5
Call MySub 4,(5),6
Call MySub
Call MySub()
Call MySub(3)

sub MySub(a,b,c) ByVal a,b,c if not isdefined(a) then a = "-" if not isdefined(b) then b = "-" if not isdefined(c) then c = "-" print a," ",b," ",c print "\n"

end sub

MySub(1,2,3) MySub 2,3,4 MySub(3),4,5 MySub 4,(5),6 MySub MySub() MySub(3) Call MySub(1,2,3) Call MySub 2,3,4 Call MySub(3),4,5 Call MySub 4,(5),6 Call MySub Call MySub() Call MySub(3)

Result executing testcall.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

2.14. recurse.bas

This program tests recursive function call of the simplest type. It actually does nothing, but calculates the number 10. It knows that 10 is assigned to 10 and that the number assigned to a number x < 10 is the same as the number assigned to x+1.

Example recurse.bas :

'
' This function calculates the number 10
' recursively
'
function Calculate10(x)

print "Starting calculate 10 for the number ",x,"\n"

if x = 10 then Calculate10 = x else Calculate10 = Calculate10(x+1) endif

print "Ending calculate 10 for the number ",x,"\n"

end function

Calculate10 1

Result executing recurse.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

2.15. msgbox.bas

This program uses the module nt and displays several message boxes. It actually displays all possible message box options, with several buttons, and signs. This program is interactive and thus it is not executed when this document is compiled.

Example msgbox.bas :

import nt.bas

nt::MsgBox """This program test the various text boxes.

In the coming message boxes press the various keys as requested by the text and check on the console window that the program reported the correct button you pressed. (Only initials are printed.) ""","Initial MsgBox"

splita " |ARI|O|RC|YN|YNC" BY "|" TO buttons splita " |W|I|Q|S" BY "|" TO marks

for j=lbound(marks) to ubound(marks)

for i=lbound(buttons) to ubound(buttons)

for d=1 to len(buttons[i]) print i," ",buttons[i]," ",j," ",marks[j]," ",d,"\n" R = nt::MsgBox(buttons[i],marks[j],buttons[i],marks[j],d) print R print

next d next i next j

2.16. testpow.bas

This program tests the power operator. The power operator is quite complex, because it is implemented to result valid result in as many cases as possible.

Example testpow.bas :

print "here comes a lot of 1:\n"
print 2 ^ 0
print -2 ^ 0
print 2.0 ^ 0
print -2.0 ^ 0
print "2" ^ 0
print "-2" ^ 0
print "2.0" ^ 0
print "-2.0" ^ 0
print
print "here comes\n2-22-22-22-2\n"
print 2 ^ 1
print -2 ^ 1
print 2.0 ^ 1
print -2.0 ^ 1
print "2" ^ 1
print "-2" ^ 1
print "2.0" ^ 1
print "-2.0" ^ 1
print " and it did!! I told you, believe me!\n"
print "here comes a lot of 4:\n"
print 2 ^ 2
print -2 ^ 2
print 2.0 ^ 2
print -2.0 ^ 2
print "2" ^ 2
print "-2" ^ 2
print "2.0" ^ 2
print "-2.0" ^ 2
print
print "2.2 ^ 2 =", 2.2 ^ 2," = ", 2.2*2.2
print
print 2.2 ^ -2, " should be the same as ", 1/ (2.2 ^2)
print
print 2.2 ^ (1/2), " should be same as ",sqr(2.2)
print
print 2.2 ^ -(1/2), " should be same as ", 1/ (2.2^(1/2))
print
print 2.2 ^ (-1/2), " last time this number"
print
print "again with strings\n"
print "2.2" ^ 2
print
print "2.2" ^ -2, " should be the same as ", 1/ (2.2 ^2)
print
print "2.2" ^ "0.5", " should be same as ",sqr(2.2)
print
print "2.2" ^ -(1/2), " should be same as ", 1/ (2.2^(1/2))
print
print "2.2" ^ (-1/2), " last time this number, ... really, I promise..."
print
print "1.0"/sqr("22E-1")
print
print "1.0"/sqr("2.2")
print
print "never trust a program! Any program, ever!\n"

2.17. testproclist.bas

This program tests the ListProcesses function of the module nt. As you can see there were quite a few processes running on my machine when I compiled this document.

Example testproclist.bas :

import nt.bas

nt::ListProcesses PS

for i=lbound(PS) to ubound(PS)

for j=0 to 8 print PS[i,j]," " next j print "\n"

next i

re::m("alma","a(.*)a") print re::format("qqq$1qqq")

Result executing testre.bas :

Possible error messages sent to stderr:

'scriba' is not recognized as an internal or external command,
operable program or batch file.

2.19. testshutdown.bas

It would be unwise to run this sample program during document compilation. To test it run it from the command line on an NT box an see it shutting down.

Oh, and do not forget: you have to have the appropriate privileges to shutdown the NT box to be successful!

Example testshutdown.bas :

import nt.bas

nt::ShutDown undef,undef,0,1,1

[Contents]

2.20. teststservice.bas

This program is not executed during the document compilation because its working has to be checked using the NT SCM. Run it on your NT box if you have one and want to use this function.

Example teststservice.bas :

import nt.bas
print """This test program starts, pauses, continues and stops
the "Removable Storage" service. After each step it waits for user input.
Check the state of the service in the SCM graphical display
pressing F5 to refresh the graphical interface and then
press ENTER in this command window to go on to the next step.
"""
            
Service$ = "NtmsSvc"
nt::StartService Service$
print Service$ & " has been started\n"
line input wait
nt::PauseService Service$ 
print Service$ & " is paused...\n"
line input wait
nt::ContinueService Service$
print Service$ & " is continued...\n"
line input wait
nt::StopService Service$
print Service$ & " has been stopped\n"
line input wait

2.21. callarg_ex.bas

This program tests,… well, er… I do not know what it tested originally. But at least it executes fine.

Example callarg_ex.bas :

sub thisfunc(a,b,c,d)

print a print print b print print c print print d print

a = "kakukk" thisfunc = "barna maci"

testvar = "kék maci"

end sub

sub thatfunc(a,b,c,d)

2.22. toolstest.bas

This program tests two function pairs from the module t. The program creates a three-dimensional array, then converts it to string and saves the string into a file. After the file is loaded into memory and converted back.

Example toolstest.bas :

import t.bas

sub PrintVar(V,level) local i,j

if IsArray(V) Then for i=lbound(V) to ubound(V) print space(level) print i,"->" PrintVar V[i],level+1 next i exit sub end if

print V,"\n" end sub

for i=1 to 5 for j=1 to 5 for k=1 to 5 a[i,j,k] = i*j*k next k next j next i

s = t::Array2StringMD5(a)

t::SaveString "savedarray.bin",s

s = undef

q = t::LoadString("savedarray.bin")

t::String2ArrayMD5 b,q

PrintVar b,1

Example trick.bas :

#! /usr/bin/scriba
print " "
a=1
call f(a+0)
print a
print
call f(a)
print a
print
function f(x)

2.53. sleep.bas

Running this program prints the numbers from 1 to 20 with 1 sec delay between them. Running this program from the documentation compilation increases the document compilation with 20 sec and is useless as we can not check interactively the delay between the printouts. Therefore here we list only the code and the result has to be checked separately.

2.58. reftest1.bas

This sample tests that though the global array is released undef-ing it the local variable a referencing it still has the value. The program should print 1undef.

 undef q
 print a
end sub
q[1] = 1

2.59. reftest2.bas

This sample allocates an array as local variable. A global variable referenced by the function argument is set to reference the array. Note that it is not the local variable a is the one that references the array, but rather the global variable that is referenced by a,namely q. If we wanted a to reference the array z then we could use undef a before the ref statement.

When the function returns the array is not released when the local variables are released, because there is a reference to it (variable q) and thje program prints the elements of q.

Example reftest2.bas :

sub test(a)
 local z,i
 for i=1 to 10
  z[i] = i
 next

ref a = z end sub

sub testi(h) test h end sub

testi q

for i=1 to 10 print i,". ",q[i],"\n" next i

This sample is the same as `reftest2.bas' with the addition that the function is calling itself recursively ten times. This time when the command ref is issued the argument is a variable referencing reference, referencing ... ten times. Still the effect has to be the same.

Example reftest3.bas :

sub test(a,s)
 local z,i

if s = 1 then

for i=1 to 10 z[i] = i next ref a = z

else

test(a,s-1)

' a becomes the same as b
ref a = b
' b is already the same as a
ref b = a
' b is undefed, but a retains the value

2.62. lettest.bas

a[1] = 1
a[2] = 1.1
a[3] = "1111111"
a[4,1] = 4
a[4,2] = 4.4

3. CGI Programs

Test programs in this chapter can not be executed in this document, therefore they are only listed here. Some of them can be executed as a CGI process, some specifically require the Eszter SB Application Engine execution environment.

[Contents]

3.1. mt.bas

This is a test program that has to executed in the Eszter SB Application Engine. This is useless being executed from the command line, and in addition being useless result extension specific error, because the CGI module can not handle the execution environment.

Start the Eszter SB Application Engine, configure it so that this program can be executed from some of the configured virtual directories and execute the program.

Note that the Eszter SB Application Engine has both the CGI and the MT modules statically linked so it has to work even if these modules are not installed on the machine.

Example mt.bas :

#!/usr/bin/scriba -c
global const nl = "\n"
Const NumberOfCookies = 3

3.2. mtlock.bas

This is a test program that has to executed in the Eszter SB Application Engine. This is useless being executed from the command line, and in addition being useless result extension specific error, because the CGI module can not handle the execution environment.

Start the Eszter SB Application Engine, configure it so that this program can be executed from some of the configured virtual directories and execute the program.

Note that the Eszter SB Application Engine has both the CGI and the MT modules statically linked so it has to work even if these modules are not installed on the machine.

Example mtlock.bas :

#!/usr/bin/scriba -c

' ' Call this program from several browsers and test locking and unlockings ' seeing how the different programs run and return an answer '

global const nl = "\n"

include cgi.bas include mt.bas
