SYSOP I've finished a lisp I've been working on, save for a way around getting the dreaded "Bad entmod list". I'm using "(setq a1 (list (assoc -1 var)(cons 39 pck)))" to change thickness of an entity (& 40 height, 41 width, etc.). I havent't been able to figure out a way to prescreen "a1" so a bad list I can then divert from going through "(entmod a1)". I realize you can use an "initget", but in some cases this would be most impractical. If I could screen the a1, obviously I could then divert the entmod statement with an "if" statement. Any suggestions on how determine this? Appreciatively, Jeff
