SYMPTOMS
REDIMing (redimensioning with REDIM) a dynamic long integer array that was passed to a SUBprogram generates a "Subscript Out Of Range" error at run time.
STATUS
Microsoft has confirmed this to be a bug in Microsoft QuickBasic Versions 4.00, 4.00b, and 4.50 for MS-DOS and in Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2 (buglist6.00, buglist6.00b). This problem was corrected in Microsoft Basic PDS Version 7.00 (fixlist7.00).
MORE INFORMATION
The "Subscript Out Of Range" occurs whether the SUBprogram is compiled as part of the main program or it is compiled in a separate module.
You can work around this problem by using an array type other than long integer, or by passing the array through a COMMON SHARED block.
The following code demonstrates the problem passing a dynamic array of long integers to a SUBprogram and REDIMing it in the SUBprogram.
REM $DYNAMIC
DIM arrayb&(50)
CALL Test(arrayb&())
END
SUB Test(arrayc&())
REDIM arrayc&(100)
END SUB
