ReplaceList() instead. This will eliminate the loop. Not sure how much
you'll gain in speed, but letting CF loop over the elements should be faster
than doing it yourself.

Subject: Help with speeding up a string replace on a large file.
> We have a case where we have 30+ instances of text in an RTF document that
need to be replaced with specific database values. The routine we have does
work, but it's pretty slow. In one case, we have a 1+ meg file, that we need
to do the 30 replacements on via the REPLACENOCASE function. This file is
taking approx 3-5 minutes to open. We've explored using REREPLACE instead,
but are not seeing any noticable speed improvement.

> 1. read file into a memory variable via the CFFile tag with action=""> > 2. Loop through our elements to replace
> 3. do an replace on the file in memory for the current element
> 4. End loop
> 5. Write the new file out to a temporary file (which we manage through
another process).

> We've used the GetTickCount function to narrow down exactly where the delay
is, and it's in the loop - not on the read and write commands.

second response time, if possible. Any suggestions?
