Repeat Commands in Macros
You can use a leading asterisk (*) to repeat a command in a macro until you
choose another command.
Once you have selected a command, you might want to use it several times
before moving on to another command. In a macro, you can repeat a command
until you choose another command. You cannot use this feature to choose
options.
If a macro begins with *^C^C, the command is repeated until you terminate
by pressing ESC on the keyboard or by selecting another command.
NOTE Do not use ^C (Cancel) within a macro that begins with the string *^C^C;
this cancels the repetition.
The macros in the following examples repeat the commands:
*^C^Cmove Single
*^C^Ccopy Single
*^C^Cerase Single
*^C^Cstretch Single Crossing
*^C^Crotate Single
*^C^Cscale Single
Each macro in the example starts a command and then prompts you to select
an object. Any other prompts necessary to complete the command are
displayed, and then the command ends and starts again.
NOTE Command repetition cannot be used in macros for image tile menus.
