Hi, I would appreciate any help anyone may offer. Let's say a text
file occasionally includes the words dogs, cats, and fleas. I need to
"read until" any of these words without skipping any. I tried the
following instruction, but of course that doesn't work:
open file FileName
read file FileName until "dogs" or "cats" or "fleas"
-- (do something with it in found order)
if it is empty then exit repeat
close file FileName
Unfortunately though, so far as I can tell, this script as-is
(obviously so wrong) reads in the whole file and doesn't stop on any
of the words.
I played with the "seek to" command but that requires a number
afterward... otherwise I would "seek to" all three of the keywords in
question and then "read to" whichever came soonest and then repeat.
Can anybody point the way? Thanks again,
