DIESEL

You can use DIESEL (Direct Interpretively Evaluated String Expression Language) to alter the
AutoCAD LT® status line through the MODEMACRO system variable. You can also use DIESEL
in menu items as a macro language instead of AutoLISP®. DIESEL expressions accept strings
and generate string results.

You can use the MODEMACRO system variable to display information on the

status line.

Overview of the MODEMACRO System Variable

The status line can provide the user with important information without

interrupting the work flow. The MODEMACRO system variable controls the

user-defined area on the status line. The calculated value of the MODEMACRO

system variable is displayed in a left-aligned panel in the status bar at the bottom

of the AutoCAD LT® window. This variable is set to the null string when you

start AutoCAD LT. Its value is not saved in the drawing, the configuration file,

or anywhere else.

The number of characters displayed on the status line is limited only by the size

of the AutoCAD LT window (and your monitor). The default panels move to

the right as the content of the MODEMACRO panel grows. It is possible to push

the default panels completely off the screen (if you want to).

You can use the MODEMACRO system variable to display, in the status line,

most data known to AutoCAD LT. With its calculation, decision, and editing

facilities you can compose the status line to your precise specifications.

MODEMACRO is a user-string variable. It can be set to any string value. The

maximum string value is 4095 characters. You can set MODEMACRO with
