let me make sure i understand you right - you want to run some sort of in-memory Zip type compression on a large text string?

if that's the case, one simple method is to write it to a file, then call some sort of external program like "gzip" to compress the file, then read the compressed file back into memory.

if you want to get a little trickier you can try giong to http://www.gzip.org/zlib/ and downloading a zlib library that might allow you to do the compression entirely in memory. i haven't played with it myself, i'm just venturing a guess.

how long are these text strings you are talking about?

Dan,

If you are looking for string compression there are VIs in the OpenG Zip Tools for doing this. The zlib library has been packaging inside of a nice set of VIs.
