Compress string

[bub]

I need to compress large strings.

I found this:

this works, but is unable to decompress sring longer than 150kb!!

you can solve?

I also found this:

but, the compression algorithm is poor and too little to reduce the immense size of my strings.

I can not work with files.

Excuse my English, I'm Italian.

you can try running 7-zip from command line using autoit's Run() function, together with 7-zip's -si and -so switches
