Thanks for the quick response. I think a little more explanation is in order on my part. I have a file with multiple concatenated sections that begin with #:lav and end with #:eof and I want to process each of these one at a time e.g.
--start of file--
#:lav
some text
#:eof
#:lav
some text
#:eof
#:lav
some text
#:eof
--end of file--
This is why I used the while loop with the concatenated string... so I can do some processing of the subsections that I find that satisfy the above criteria. Writing a while loop to process the code line by line would be more efficient in memory, but more time in development.
