Batch variable inside of variable

It looks like that (and it won't work)

set currentvar=5
set maxvar=9
set p1=aaa
set p2=bbb
set p3=ccc
set p4=ddd
set p5=eee
set p6=fff
set p7=ggg
set p8=hhh
set p9=iii
set /a result = %maxvar% - %currentvar%
echo Found %result% vars in the range.
:LOOP
if %currentvar% LSS %maxvar% (
set /a currentvar=%currentvar% + 1
echo %p %currentvar% % //IT WON'T WORK AND I DON'T KNOW HOW TO MAKE IT WORK...
goto LOOP
) else (
goto END
)
:END

The result I'd like to see:

fff

ggg 

hhh

iii

this might work for you:

@ECHO OFF &SETLOCAL
set /a currentvar=5
set /a maxvar=9
set /a RangeStart=currentvar+1
set p1=aaa
set p2=bbb
set p3=ccc
set p4=ddd
set p5=eee
set p6=fff
set p7=ggg
set p8=hhh
set p9=iii
set /a result=maxvar-currentvar
echo Found %result% vars in the range.
for /l %%a in (%RangeStart% 1 %maxvar%) do call echo(%%p%%a%%

You need to Enabledelayedexpansion:

@echo off
Setlocal Enabledelayedexpansion
set currentvar=5
set maxvar=9
set p1=aaa
set p2=bbb
set p3=ccc
set p4=ddd
set p5=eee
set p6=fff
set p7=ggg
set p8=hhh
set p9=iii
set /a result = %maxvar% - %currentvar%
echo Found %result% vars in the range.
:LOOP
if %currentvar% LSS %maxvar% (
set /a currentvar=%currentvar% + 1
echo !p%currentvar%! &REM This is how you make a comment in batch
goto LOOP
) else (
goto END
)
:END
Endlocal

And that should do what you want to do. Also to make a comment use a new line and type :: or REM.
