Need advice how to.

[phoenix_1]

If I receive from PC to PicMicro next:

receive var byte[8]
hserin [STR receive\8]

then I will receive "128ABCDE"
And I will have next:

receive[0] = "1"
receive[1] = "2"
receive[2] = "8"
receive[3] = "A"
receive[4] = "B"
receive[5] = "C"
receive[6] = "D"
receive[7] = "E"


How to I get from that as decimal 128 separated from ABCDE ?
I was probe and get result from receive[0] is dec 49 and that is ASCII chr.....

Core of my try is to thel PicMicro what to show on LCD at position what I want.

Org of my LCD is 4x20 chr with No:. of position from 128 to 231..

Are you putting a "#" in front of the variable some place? If I am not mistaken,
#1 would be 49

No but if I simple want to do next:
lcdout $fe,128+X,"ABCDE"
where X= 1 from string (bit0 ) I was see that cant be becouse Pic see that as 128+ASCII value and that cant we do!
After that I was probe to get DEC value from ASCII (1) waht was come from PC in message "128ABCDE" and see that byte[0] = "1" and really value for that is DEC 49 .
Or HEX $31 .
I need formula hove I translate $31 to dec 1 or any HEX to dec value...
HEX or ASCII to real integer.

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...
