how can i give a variable to a case like this?

[nnnmmm]

Code: Select all

AA=
SET P1=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATTTTTTTTAAAAAA
SET P2=NNNNNNNNNNNNNNNNNNNAAAAAAAAAAAAAAA
SET P3=AAAAAADDDDDDDDDDDDDDDDDAAADDDAAAAAAAAAAAA
ECHO 1. %P1:~0,78%
ECHO 2. %P2:~0,78%
ECHO 3. %P3:~0,78%

how can i give a variable to a case like this for an easy control?

Code: Select all

BB=
SET AA=50
ECHO 1. %P1:~0,AA%
ECHO 2. %P2:~0,AA%
ECHO 3. %P3:~0,AA%

BB= doesnt work because it doesnt do ECHO 1. %P1:~0,%AA%%

Either like this:

Code: Select all

SET "P1=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATTTTTTTTAAAAAA"
SET "P2=NNNNNNNNNNNNNNNNNNNAAAAAAAAAAAAAAA"
SET "P3=AAAAAADDDDDDDDDDDDDDDDDAAADDDAAAAAAAAAAAA"

SET "AA=26"
SETLOCAL ENABLEDELAYEDEXPANSION
ECHO 1. !P1:~,%AA%!
ECHO 2. !P2:~,%AA%!
ECHO 3. !P3:~,%AA%!

Or like this:

Code: Select all

SET "P1=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAATTTTTTTTAAAAAA"
SET "P2=NNNNNNNNNNNNNNNNNNNAAAAAAAAAAAAAAA"
SET "P3=AAAAAADDDDDDDDDDDDDDDDDAAADDDAAAAAAAAAAAA"

SET "AA=26"
CALL ECHO 1. %%P1:~,%AA%%%
CALL ECHO 2. %%P2:~,%AA%%%
CALL ECHO 3. %%P3:~,%AA%%%

>CALL ECHO 1. %%P1:~,%AA%%%

why do you need "call" in there? i thought it worked because it had the correct % numbers, but it was the call that did it, somehow my brain ignored the word "call" everywhere and tried ECHO 1. %%P1:~,%AA%%% in a new batch and it didnt work. just strange how brian works.

copy paste to test the code?
then i actually write it in a different syntax.....
