SET P1=AAAABBBBBBBB DDDDDDDDDDDDDDDDDAAAAAAAAAAAAAAAAA

AA=works in ztreemenu
ECHO %P1:~0,78%

BB=works in command line but not in ztreemenu as it was meant to
SET N=20
ECHO %%P1:~0,%N%%%

CC=doesnt work in ztreemenu, i think it is a bug in ztree
so i started adding more %'s hoping it to work, but no luck so far

SET N=20
ECHO %%%P1:~0,%N%%%% no work in ztree
ECHO %%%P1:~0,%%N%%%% no work in ztree
ECHO %%%P1:~0,%%N%%%%% no work in ztree

how can i make it work?

but without using delayed expansion... which i havent tried yet

sometimes adding 1 more % doesnt work, and i have been blindly adding %'s until it worked, then it worked, but no luck with AA=
