hey pal, youve been reading "how to make friends and influence people" no-one appreciates swearing.

anyway...
Winzip uses a "dictionary" of regularly occurring strings and uses a bookmark as a reference to it like this....

"AAAAAAABBBBBBBBCCCCCCCCBBBBDDDDDD"

the dictionary looks like...

X1 = A
X2 = BBBB
X3 = CCCCCCCC
X4 = DDD
so the compressed string....
"7X1 2X2 1X3 1X2 2X4" or something like that, it becomes more apparent in bigger strings.

thats one way of doing it

I made something like this... it doesn't compress a string it encrypts it but you could probably just use numbers then convert it to a constant 23838328E+.383393 or whatever then convert that to a double or whatever and extract each characteryou'ld have to make for example 65 A to 065 because there are 255 possible
