7. REPEATING COMMANDS
You can repeat many immediately preceding command by TYPEing ENTER on the keyboard or CLICKing the ENTER button on the cursor device. Unfortunately, the OEM version of AutoCAD® that is running C.P.M. is somewhat erratic about this function. Some commands repeat using ENTER, some do not. You will discover which these are.
Try to train yourself to use the cursor device ENTER button at any time it will work.
8. SEQUENTIAL COMMAND STRINGS
Many of the C.P.M. commands run in a "command sequence" of steps which require input information for each step. These steps are usually executed by choosing an object or a desired point on the screen with a cursor and clicking the SELECT button on the cursor device. These commands automatically complete themselves when the last step has been SELECTed. For example, the MOVE command begins with:
The "Select objects:" mode will repeat until you CLICK ENTER. Then the computer say:
Base point or displacement:
and after you SELECT that point, it will say:
Base point or displacement: Second point of displacement:
After you SELECT this point the MOVE command automatically ends.
MEMORIZE THIS CONCEPT: When working within a sequential command string =
1. If you are choosing a place (point) on the screen, use the SELECT button.
2. If you are changing to the next part of the command sequence or ending the command, use the ENTER button.
9. CANCELING A COMMAND
C.P.M. allows you to correct mistakes quite easily. Until you have ENTERed, if you realize that you have typed the wrong command or misspelled a command, just back-space as you
