Need advice how to.

[phoenix_1]

OK, misunderstanding.
I seem to remember this

X1 = (NUMS[1]-"0")

The -"0" is what you need.
I think

Here is my success test of geting index from array.
After geting and ading decimal integer from example "10ABCDEF"
x3 will be decimal 10 and i can add it with 128(first place on first line on 4x20 LCD...
And there I can display rest of sting from array "ABCDEF"...
Thank's to all who make me to little more think with my head...
