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
2.1. testnt.bas
This test some functions of the module NT.
Example testnt.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
import nt.bas
Result executing testnt.bas :
Possible error messages sent to stderr:
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.
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

Possible error messages sent to stderr:
2.3. const.bas
This program test the difference local (module local) and global constants.
Example const.bas :
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"
module TEST
a = "VARIABLE"
Global Const a = "a "
Const b = "b "

2.5. gdtest.bas
This program creates a file `test.png' with some graphics in it.
Example gdtest.bas :

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 :
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

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 :
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"

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 :
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"

print R

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

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.

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 :
ref a = z
