Toggling a check mark in a menu via lisp

[Aviv_Eyal]

I am trying to add an on and off  checkmark via lisp to an item in a pull down menu.

a know it can be done with diesel but only on system variables.

in my case i can't use sysvars - only lisp.

i tried (menucmd ....) but I get nil.

 any suggestions will be great

thank

what i ment is somthing like this in diesel:

$(if,$(getvar,dimaso),!.)/vAssociative Dimensions]'_dimaso
$M=$(-,1,$(getvar,dimaso))

yet i don't want to use disel because it only uses system variables.

I want to program it in lisp using menucmd but i gust can't get it right....

Aviv,

sorry, but I can't be much help in this issue.

Which AutoCAD version are you using, DIMASO was replaced by DIMASSOC...

"...to add an on and off checkmark via lisp to an item in a pull down menu"

What will the on/off checkmark represent?  Is this to affect a sysvar or other option setting?

"...in my case i can't use sysvars - only lisp..."

Why can't you use sysvars?  (Does this mean you can't use SETVAR in a LISP routine?)

And, finally, assuming this is for something entirely custom, maybe DOSLib (http://www.en.na.mcneel.com/doslib.htm) has a function that will help.
