XMS Memory with MS-DOS Shell Task Swapper (74465)

Applications running under MS-DOS Shell with Task Swapper enabled
cannot allocate XMS memory unless you specify a value in the "XMS
memory required" option. This is done to prevent Task Swapper from
having to swap unused XMS memory to disk. Programs will be unaware of
the existence of XMS memory, and the MEM command will report 0 (zero)
bytes of available XMS memory.
XMS memory can be specified for a task by specifying a value in the
XMS Memory KB Required option of the Advanced dialog box, as follows:
• From the program list, select an application.
• From the File menu, choose Properties.
• From the Program Item Properties box, choose Advanced.
• In the XMS Memory KB Required box, insert the amount of XMS memory
that you want to be available to the program.
• Choose OK as many times as you need to return to Shell.
Whenever Task Swapper is enabled, that application can access XMS
memory up to either the limit specified in the XMS Memory Required box
or the XMS Memory KB Limit box, whichever is greater.
NOTE: Some XMS memory must be specified in the XMS Memory Required
