I'm making a program that would encrypt a paragraph. Im using the variable expansion thingy (%variable:~1%) to find each letter and echo it as a different letter. But I do not want a limit to the amount of LETTERS that you can type in and don't want to write a overly LARGE code. Does anybody know how to include another variable in a variable expansion thing?
%var1:~%var2%% did not work.maybe you can find something here>http://www.robvanderwoude.com/index.htmlUse the following as a template. The key is to CALL the SET

Code: [Select]
SET start=10
SET length=9
SET string=The quick BROWN fox jumps over the lazy dog
CALL SET substring=%%string:~%start%,%length%%%
ECHO (%substring%)


Hope this helps. Thanks. The call trick works perfectly! I finished my rough draft of my encoder. Basic code right now. See if you can BREAK it!

Ive also made a decoder. If you want to find out how I made it email me, or if you want a copy. I'll also check the forum.*censored*! I left my magic decoder RING in my other suit. But in the neverending quest for knowledge, why don't you post your solution so everyone see your handiwork.
