Ummm...I'm not a professional programmer or anything but I do believe that plain vanilla Perl or any other language doesn't care too much about the data types that have been laid out in a datafile which (I assume) is binary. This is all just a concept based on the type of format that the writing program has used to write out the stream which (hopefully) you have some clue to...
Sorry, but I think you need to include more information or an example or something.

i think what you mean is, you want to search the contents of a file(s) and check to see if you find a match, right?
if so try this:
open (SEARCH, "path/to/myfil.dat"
;
for($i = 0; <SEARCH>; $i++)
{
$file_contents[$i] = $_;
if ($search eq $file_contents[$i])
{
Do you stuff here
END;
}
}
close (SEARCH);
that should open the file, and put it into an array for you (handy for later) and then match up your search string to each of those array elements until/unless it finds one that matches where it should end. What ever you want to do with the data you've matched up, do inside the if loop (print it out/whatever) if your doing the program i think, (webmnkeys tutorial - the move library/review?) then this should be a sinch
Good Luck

thanks al!
yes, after i submitted it i realized that i was much to vague..especially after reading some of the other posts. anyways, here is the main task that i am trying to accomplish...
i will have an html document with patterns such as this
6.3.2.1 T_THI
7.3.2.3 G_G
5.2.3.3 S_SH
but many of them...and they refer to a definition later in the doc and i'd like to link them together..so i need a program to reference the letter combination with the corresponding number..then set a source at the location above and a target at the definition later in the document.....
THANKS!

hi
just to be clear..i'll use an example. it would be like making a source link on the T_THI to 6.3.2.1, in many cases more than one, whereever T_THI occurs...and then making the 6.3.2.1 a target in the definitions section....i may split up the docs to do this if it would be easier to do in two programs..anyone have any ideas?
thanks!
