Cancel Running Commands

Make sure that you have no AutoCAD LT commands in progress before you

execute a macro. To automatically cancel a command before executing a

macro, enter ^C^C at the beginning of the macro (which is the same as pressing

ESC twice). Although a single ^C cancels most commands, ^C^C is required to

return to the command prompt from a dimensioning command and ^C^C^C

is required based on the current option of the Layer command. ^C^C handles

canceling out of most command sequences and therefore is the recommended

sequence used to ensure no command is active before the macro is started.

Verify Macro Characters

Every character in a macro is significant, even a blank space.

When you place a space at the end of the macro, AutoCAD LT processes the

macro as though you had entered a command (circle, for example) and then

pressed the SPACEBAR to complete the command.
