Topic: Wildcard values in lisp question

[diarmuid]

Look at the part of a lisp I have written below

At one part of the lisp, it checks to see if the file  a particular number.  If so, then it quits.
The list of drawings shown below is much, much longer than shown, but you get the idea.

Code: [Select]


(setq pfdcheck (getvar "dwgname"))

(if      (or
                    (= pfdcheck "WN49090010001.dwg")
                    (= pfdcheck "WN49090010002.dwg")
                    (= pfdcheck "WN49090010003.dwg")
                    (= pfdcheck "WN49090010004.dwg")
                    (= pfdcheck "WN49090010005.dwg")
                    (= pfdcheck "WN49090010006.dwg")
                    (= pfdcheck "WN49090010007.dwg")
                    (= pfdcheck "WN49090010008.dwg")
                    )
             
               
               
               (progn
                    (prompt "\nNot a P&ID Drawing.")
                    (prompt "\n ")
                    (princ)
                    (quit)
                                     
               );end progn
        )





What I’m wondering is, can I do a wildcard type scenario.  The first 10000 series drawings have been reserved for PFD’s, and I want to exclude them from the next part of the lisp.

So what I’m trying to convey is  could I do something like:

(= pfdcheck "WN4909001****.dwg")


Instead of having a long list of drawings that i have to manage as new files get added.

Any help or hints would be greatly appreciated

Hi,

Look at the wcmatch LISP function topis in the developer's help.

# (pound)   Matches any single numeric digit.

Code: [Select]

(wcmatch pfdcheck "WN4909001####.dwg")
