SUMMARY
=======
 
Road Atlas for MS-DOS provides a valuable memory troubleshooting tool.
The information can be accessed from the Help menu by choosing the
About command. The values listed at the bottom of the screen, and to
the right of the Memory heading, are useful for troubleshooting
memory issues that adversely affect product performance.
 
The report is divided into four parts:
 
   Memory: <1>K + <2>K + <3>K + <4>K EMS
 
where:
 
   1 is free memory reported by MS-DOS.
 
   2 is the amount of memory taken by the Road Atlas databases.
 
   3 is the amount of memory in the Road Atlas memory pool. The value is
   reported in blocks of 3K.
 
   4 is the amount of Expanded Memory Specification (EMS) used by Road
   Atlas (maximum value of 3200K).
 
MORE INFORMATION
================
 
When you interpret the Memory report, the most useful value is the
amount of memory in the Road Atlas memory pool. If this value is
below 60K, Road Atlas runs very slowly and you may receive out of
memory messages or Stack Overflow errors.
 
Program functionality will be limited if the value is below 30K. For
example, printing enhanced maps may fail and you may receive out of
memory errors. The error messages change with the version of Road
Atlas for MS-DOS. For example, earlier versions produce a Stack
Overflow error; however, Road Atlas for DOS version 3.02 displays an
Out Of Memory message.
 
Evaluate the installed terminate-and-stay-resident (TSR) programs and
remove unnecessary TSRs from the system. Configure the system to
allow the maximum amount of free Extended Memory (XMS).
