Title: String/list compression in basic
Post by: josephmarin on July 12, 2007, 08:34:00 pm

I'll be needing some compression for FFROS, as you know dialog is a large chunk of bytes. So string compression would be usefu, and im worthless with compression. Could someone show me how it would be done? code would be appreciated. Thanks!

Here is how you do string - list:
seq(Instring("ABCD...",sub(str1,A,1)),A,1,length(str1)-> L1

EDIT:
Here is a way to convert the list to string:
ClrHome
" /->/ Str2
"ABCDEFGHIJKLMNOPQRSTUVWXYZ? ./->/Str1
For(A,1,dim(L1
Str2 + sub(Str1,L1(A),1 /->/Str2
End
