When the SHELL statement is executed, some portions of the BASIC
run-time module (BRUNxx.EXE) are unloaded. This is done to free up as
much memory as possible for COMMAND.COM. When the SHELL is complete,
the run-time module must be reloaded.

This information applies to Microsoft BASIC Compiler Versions 6.00 and
6.00b for MS-DOS and MS OS/2, Microsoft BASIC Professional Development
System (PDS) Version 7.00 for MS-DOS and MS OS/2, and to Microsoft
QuickBASIC Compiler Versions 4.00, 4.00b, 4.50 and earlier for MS-DOS.

If the run-time module is located on a floppy disk removed during the
SHELL statement, it must be re-inserted before the BASIC program can
continue. If the program cannot find the run-time module, it will
prompt you for its location.

To avoid the need to reload the run-time module after SHELL, you can
compile with the /O (stand alone) option, which includes the run-time
routines into the BASIC .EXE program at LINK time.
