This program tests,… well, er… I do not know what it tested originally. But at least it executes fine.
Example callarg_ex.bas :
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)
print "testvar is ",testvar
end sub
print "haho!!!\n"
sub thisfunc(a,b,c,d)
Result executing callarg_ex.bas :
