I adapted Marty del Vecchio's swap procedure for PowerBasic, and it
works fine.
The package (swap) includes a MS-DOS assembly-language routine that can
be called from a PowerBasic 3.1 program.  It will swap most of the
current program  to extended memory (supplied by an XMS driver, such as
HIMEM.SYS), expanded memory (EMS version 4.0), or disk, thus freeing up
more memory for DOS. It will then execute another program in its place,
and re-load the original program to its original state.  This allows
large DOS programs to execute other programs without the original
program taking up DOS memory.
Interested?
