I recently had an issue with one of my batch programs, it is basically an incompleted platformer: My code is work in progress and i got stuck with my attemp of collision detection. I have a matrix M, that i can access within an EnableDelayedExpansion block like this !M[%%a][%%d]!
The first time it works, but the second usage does not work anymore:
echo A!M[%xx%,%yy%]!B yields AB.
I would appreciate any hint.
Thanks in advance!

I would like to call variables that contain other variables in their name when I have enabledelayedexpension so I would have concentric exclamation points in my variable call.
I apologize for the unclear wording; I'm not very familiar with this subject.
Here's a portion of my code that shows my issue:
set /a Freq[%%z]value[!value!]+=%%y
echo Freq %%z value !value! is !Freq[%%z]value[!value!]!
As is, batch interprets !Freq[%%z]value[!value!]! broken up into different variables with the !'s, and I don't think I can use %'s instead because I'm in a for loop where this variable is changing. I don't think I can use another for loop to replace !value! with a %%a either.
Here's a more complete look at my code:
set /a line=0
set /a goodLine=0
FOR /F "tokens=* delims=" %%x in (%file%) DO (
set /a line+=1
echo Line is !line!
set data[!line!]=%%x
set /a value=0
set /a checkGood=0
FOR %%y in (%%x) DO (
set /a value+=1
if !value!==1 (
set /a Freq=%%y
set /a checkFreq=%%y %% 10
if !checkFreq!==0 (
set /a checkGood=1
) else (echo bad)
) else (
if !checkGood!==1 (
for /l %%z in (40, 10, 330) do (
if !Freq!==%%z (
set /a Freq[%%z]value[!value!]+=%%y
echo Freq %%z value !value! is !Freq[%%z]value[!value!]!
set /a Freq[%%z]quantity[!value!]+=1
echo Freq %%z value !value! quantity is !Freq[%%z]quantity[!value!]!
)
)
) else (echo checkGood bad)
)
)
)
#ECHO OFF

Or you could use a for/f "tokens=2delims==" %%e in ('set Freq[%%z]value[!value!]') do echo %%e
depends on what you really want to do.
I couldn't get %difference_two% to work It can find %difference_one% as 2 but when I make it divide 2 by 2 it doesn't display as anything.

In batch, commands in a code block (between ( )) are interpreted as on the same line, so you need to use setlocal EnableDelayedExpansion and use ! instead of % inside them.

I made this awesome (horrible) Rubik's cube scrambler a while ago, but when I look at the code, it's just too much, I know there is a very simpler way of doing this. If there is anyone who can modify certain bits to make the code more compact, I would really appreciate it.
This is purely for my understanding in batch, and hopefully others can learn from anything you answer.
Here is the code:

Good Afternoon!
Long time reader, first time poster! I have been having a lovely time trying to modify a working batch file to account for variability. The situation is that I have a variable-size text document that normally would be able to be split into sections of 252 lines. The code below worked like a champ:
#echo off & setlocal EnableDelayedExpansion
set param=%*
if not defined param (
echo.
echo. Usage: batchsplit [device:][pathname]filename
goto :EOF
)
set param=%param:"=%
if not exist "%param%" (
echo.
echo. File "%param%" not found
goto :EOF
)
for %%j in ("%param%") do (
set name=%%~dpnj
set ext=%%~xj
)
for /F %%j in ('type "%param%" ^| find /V /C ""') do set Full=%%j
set /A Split=%Full%/252
for /L %%G in (1,1,%Split%) do type nul > "%name%_%%G%.new"
set X=1
set N=1
set Q=1
set limit = 252
for /F "tokens=1* delims=]" %%j in ('type "%param%" ^| find /V /N ""') do (
set /A N+=1
set /A Q+=1
echo.%%k>> "%name%_!X!%.new"
if !Q! gtr 252 (
set /A X+=1
set /A Q=1
) else if !N! gtr Full (goto theend
)
)
:theend
echo split into %split% files with 252 lines each
rem pause
However, there were some changes to the formatting of the text, and now instead of four pages of 63 lines per split file, it can be completely variable. The only constant is this final line, which precedes the remaining space for a 63 line page:
ON THIS FORM IS COMPLETE AND CORRECT AS NOTED:___________________
Note that there is a single space in front of it, as well as multiple spaces, a colon, and underscore characters. Being the meathead that I am, I thought I could insert an if-then statement into the for loop to trigger the batch to split to the next page. However, I could be further from that right now. This is the code I have been smashing my head with:
rem #echo off & setlocal EnableDelayedExpansion
setlocal EnableDelayedExpansion
set param=%*
if not defined param (
echo.
echo. Usage: textsplit [device:][pathname]filename
goto :EOF
)
set param=%param:"=%
if not exist "%param%" (
echo.
echo. File "%param%" not found
goto :EOF
)
for %%j in ("%param%") do (
set Name=%%~dpnj
set ext=%%~xj
)
for /F %%j in ('type "%param%" ^| find /V /C ""') do set Full=%%j
set stopvar= ON THIS FORM IS COMPLETE AND CORRECT AS NOTED:___________________
set Split=1
echo %stopvar%
set X=1
type nul > "%name%_!X!%.new"
set N=1
set Q=1
set S=0
set L=63
for /F "tokens=1* delims=]" %%j in ('type "%param%" ^| find /V /N ""') do (
set /A N+=1
echo %N%
set /A Q+=1
echo %Q%
echo.%%k>> "%name%_!X!%.new"
if ["%%k%" == "!stopvar!"] (
set /A S+=1
)
if !Q! gtr !L! (
if !S! == 1 (
set /A X+=1
set /A Q=1
type nul > "%name%_!X!%.new"
set /A Split+=1
set S=0
)
else set /A L+=63
else if !N! gtr Full goto theend
)
:theend
echo Split into %split% files!
pause
The premise is that every 63 lines, the stop variable (S) is checked. If it is off (0) then the batch will continue to write for another 63 lines (one page). If the stopvar matches the line that is being read by the for loop, S becomes 1. When the program checks again, it will create a new file and begin writing to that new file. Right now, based on turning off #echo off the hangup is at the for loop. See below:

As I posted in the comment above, this is just a variation of the first answer that accounts for blank spaces if they are needed to keep the output files from having unnecessary whitespace on top. This is especially helpful when a print manager is just spitting out whitespace until the end of the page before starting the next part instead of going straight to the next portion.
So I've been writing a batch file which backs up a certain file while cleaning old entries every so often. I've run into an issue where it would be simpler and more readable to store month lengths (for calculation purpose) (days1,days2,days3,etc.), and reference these by concatenating the word days with a variable which stores the month (1, 2, 3, etc.). Unfortunately, this never seems to reference the right variable correctly. Here's the relevant code, from a section calculating a date 28 days previously:
set days1=31
set days2=28
set days3=31
set days4=30
set days5=31
(etc.)
...
set pastmonthday=%curday%-28
set pastmonthmonth=%curmonth%
set pastmonthyear=%curyear%
if %pastmonthday% lss 0 (
set /a pastmonthmonth=%pastmonthmonth%-1
set /a pastmonthprevmon=1
)
if %pastmonthmonth%==0 (
set /a pastmonthyear-=1
set /a pastmonthmonth=12
)
set monthlengthvar=0
setlocal EnableDelayedExpansion
set tempmonthlengthvar=0
if %pastmonthday% lss 0 (set tempmonthlengthvar = !days%pastmonthmonth%!)
echo.%tempmonthlengthvar%
pause
for /F "delims=" %%A in (!tempmonthlengthvar!) DO (
endlocal
set "monthlengthvar=%%A"
)
set pastmonthday+=%monthlengthvar%
echo.%pastmonthday%
pause
...
The two echoes output 0 and -7, respectively. I can't figure out why this is, no matter how I've reworked it.
