DIESEL Expressions in Macros

You can use DIESEL string expressions in customization (CUI) files as an

additional method of creating macros.

These expressions can return string values (text strings) in response to standard

AutoCAD LT commands. They can also return string values to the menu itself,

thereby altering the appearance or content of a menu label.

A DIESEL expression that you use in a menu item must follow the

$section=submenu format where the section name is M and the submenu is

the DIESEL expression you want.

Consider the following example:

^C^C^P$M=$(if,$(=,$(getvar,cvport),1),mspace,pspace)

This string provides a way to toggle between paper space and model space if

TILEMODE is set to 0. This expression is evaluated transparently. If the special

character ^P (which toggles MENUECHO on and off) is omitted, the expression

displays only the issued command.
