All, I can't find the answer to this anywhere, and I would
appreciate some help. I'm reading lines out of an address
book file. I know what the last line of each entry is
(there is also a blank line between each entry). I want to
read certain information out of each listing, then perform
some other functions before going on to the next listing.

So I was thinking of using a while loop to do it, but I'm
not sure of the syntax. Trying the "not equal" like this
doesn't work:

while ((substr$_,0,19)<>~/objectclass: person/) {
    ....
}


I could also key off the blank line between listings instead
of the last line of the listing, but right now I'm too fried
to think how. Thanks for your help (and patience!).
