Entering the ESPEED command in a batch file

You may want to run the ESPEED program by including the

command in a batch file. For example, if you have a program
called SLOWDOWN which requires a slower processor speed,

you could include the following commands in a batch file to

start the SLOWDOWN program:

ESPEED L

SLOWDOWN

You could name the batch file SLOW.BAT. Whenever you

need to run the SLOWDOWN program, insert the program
diskette in drive A. Then type S

LOW

and press

Enter. The

computer changes the speed to low and starts the
SLOWDOWN program.

See your MS-DOS Reference Manual for instructions on

creating and using batch files.
