Lisp Routine help

[pryzmm]

hi everyone ,

i got this nice routine lisp from another site, basically it do drawing cleanups, with layer purging,,,in it's user input it ask all the layer to be (thaw, on & unlock) so it could complete its cleanups, theres no problem with it except that i will have to manually freeze, lock & off those i needed to be that way after the routine.

question:

is there a string i could incorporate into the "cleanup lisp" to remember all the current layer state (frozen,lock,off,,,etc), store them before the main "clean up" routine runs, and since this clean up may delete (purge) those layer which is not used in the drawing and maybe "frozen" or "off" earlier, i need the "restore" string routine to ignore this and go ahead in restoring those layer that remains, after,,, does this make any sence ???

if theres one could anyone provide me the string,,,,pls.

with thanx in advance,,,,
