    Default Need help with my lisp routine


    I am currently updating a lisp routine for work but I haven't been doing any lisp programming for a long time and I have a hard time to fix this one and wonder if anyone could help.

    The original routine was used to automatically ask to update the title block of our drawings unless the the block attribute "FRMDATE" was equal to Aug 15/2000.

    We just created a new set of title block and now want the routine to work the say way unless "FRMDATE" is equal to Aug 15/200 or Mar 31/2006.

    Here is the original lisp text
    ;                            AutoCad/AutoLisp
    ;   Purpose: To check for out of date formats
    ;   Note: Updates block definitions only...does not
    ;          re-insert block instances.  Therefore attributes
    ;          not re-created and could be in OLD locations if
    ;          moved in latest definition.
    ;   Rev.  Date:     By:  Description:   
    ;   1.00  Oct 09/00 PTD  -Acad2000 compliant.
    ;   1.10  Nov 09/00 PTD  -added check for formats without FRMRDATE

    If you're creating a new set of title blocks, then I strongly advise you to implement title block attributes, with Fields mapped to a Sheet Set's custom Properties.

    Thanks for your advice.

    I would still like to use this lisp program cause it give us a warning on the screen when we open old drawings with title blocks that are obsolete. (attribute "FRMDATE" not equal to Aug 15/2000 or Mar 31/2006)

    We just don't want that warning sign to show up when the attribute "FRMDATE" is equal to Aug 15/2000 or Mar 31/2006 and I was thinking there was probably a way to quickly modify the code.

    It's working fine right now with a single value (Aug 15/2000) for date_str but how can I assign an additional value (Mar 31/2006) ?

    Any idea ?

    The simplest revision I can see would be to change

    (setq date_str "Aug 15/2000"

    (setq date_str (list "Aug 15/2000"  "Mar 31/2006")

    (if (= (dxf 1 ent2) date_str)

    (if (member (dxf 1 ent2) date_str)

    Made the changes and everything works fine.

    Thank you so much !
