Q57646: Use STACK, Not FRE("), with QBX.EXE or /Fs in BASIC 7.00
Article: Q57646 Product(s): See article Version(s): 7.00 | 7.00 Operating System(s): MS-DOS | OS/2 Keyword(s): ENDUSER | | mspl13_basic Last Modified: 14-JAN-1990 With the advent of far string support in Microsoft BASIC Professional Development System (PDS) Version 7.00 for MS-DOS and OS/2, the FRE() function has some different properties. The following statement PRINT FRE("") does not return the remaining default data segment (DGROUP) space when run in the QBX.EXE environment or when run as a program compiled with the /Fs (Far String) option. To obtain the remaining DGROUP space in these cases, you must now use the STACK function (introduced in BASIC 7.00). For example, the following statement PRINT STACK returns the current space available in DGROUP for the STACK to be resized. The stack is always in DGROUP, so the new STACK function conveniently informs you of the total remaining space that can be used in DGROUP. This information applies to Microsoft BASIC PDS 7.00 for MS-DOS and MS OS/2. For more information on the many changes in the FRE() function in regard to far strings, refer to Pages 140-142 of the "Microsoft BASIC 7.0: Language Reference" manual.
