SUMMARY
MS-DOS Versions 4.00 and later take 30K or more memory than MS-DOS Versions 3.x. As a result, a memory-intensive application that successfully compiled and executed under MS-DOS Versions 3.x may fail to run under MS-DOS Version 4.00.
You can check if the problem is caused by memory limitations by adding a SETMEM(-30000) to the beginning of the program and running under MS-DOS Versions 3.x. If the program runs out of memory with this test, it may fail with MS-DOS Version 4.00.
This information applies to Microsoft QuickBasic Versions 4.00 4.00b and 4.50 for MS-DOS, to Microsoft Basic Compiler Versions 6.00 and 6.00b for MS-DOS and MS OS/2, and to Microsoft Basic PDS Version 7.00 for MS-DOS and MS OS/2.
