SYMPTOMS
========


If a third-party memory manager has optimized memory by using specific loading
programs or parameters within batch files, the following error message is
displayed after you run MemMaker:

   Bad Command or Filename

NOTE: You may also receive error messages from the third-party expanded memory
manager (EMM) if commands such as LOADHI (from QEMM) are called.

CAUSE
=====

Some third-party memory managers optimize one or more levels deep in batch files
called from the AUTOEXEC.BAT file, trying to load programs in upper memory.
MemMaker does not analyze software called from batch files within the
AUTOEXEC.BAT file, but instead treats the whole batch file as one entity and
attempts to load it in upper memory.

WORKAROUND
==========

If you receive error messages because commands specific to third-party EMMs are
still in your batch files, edit the files and remove the third-party specific
information.

For example, if you have the following QEMM command in a batch file called from
the AUTOEXEC.BAT file, you receive the following error message after you run
MemMaker:

   LOADHI /R:2 doskey /insert

To work around this problem, remove the QEMM-specific information. For example:

   doskey /insert
