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.
