 Q. How can I tell, from a batch file, if 386MAX is installed? A. DOS provides a batch file command to identify the presence of any    resident software in the system.  The following batch file, TEST.BAT,    shows how to use DOS's IF EXIST command to do just that.  In addition,    TEST.BAT will also determine if EMS services are available. 386MAX is (c) Copyright 1990, Qualitas, Inc.
