The following code will split a string with N number of substrings with   separated values  You can use any delimiter   echo off if   1        goto error1  set  myvar   1    FORLOOP For  F  tokens 1  delims      A IN    myvar   DO       echo   A     set  myvar    B      if NOT    myvar       goto FORLOOP    goto endofprogram  error1 echo You must provide Argument with   separated  goto endofprogram  endofprogram

If someone need to split a string with any delimiter and store values in separate variables  here is the script I built   FOR  F  tokens 1 2 delims x   i in   1920x1080   do     set w  i   set h  j   echo  w  echo  h    Explanation   tokens  defines what elements you need to pass to the body of FOR  with token delimited by character  x   So after delimiting  the first and second token are passed to the body  In the body  i refers to first token and  j refers to second token  We can take  k to refer to 3rd token and so on    Please also type HELP FOR in cmd to get a detailed explanation

Three possible solutions to iterate through the words of the string   Version 1    echo off  amp  setlocal set s AAA BBB CCC DDD EEE FFF for   a in   s   do echo   a   Version 2    echo off  amp  setlocal set s AAA BBB CCC DDD EEE FFF set t  s   loop for  f  tokens 1     a in    t    do      echo   a    set t   b      if defined t goto  loop   Version 3    echo off  amp  setlocal set s AAA BBB CCC DDD EEE FFF call  sub1  s  exit  b  sub1 if   1      exit  b echo  1 shift goto  sub1   Version 1 does not work when the string contains wildcard characters like     or       Versions 1 and 3 treat characters like          or     as word separators  These characters have the same effect as the space character

Here is a solution based on a  function  which processes each character until it finds the delimiter character   It is relatively slow  but it is at least not a brain teaser  except for the function part       Example  1  set data aa bb cc echo Splitting off from   data    call  split once   data        left   right  echo Split off   left  echo Remaining   right  echo      Example  2  echo List of paths in PATH env var  set paths  PATH   loop     call  split once   paths        left   paths      if   left   equ    goto loop end     echo  left  goto loop  loop end       HERE BE FUNCTIONS goto  eof     USAGE       call  split once  string to split once   delimiter char   left var   right var   split once     setlocal     set right   1     set delimiter char   2     set left       if   right   equ    goto split once done       split once loop         if   right  0 1   equ   delimiter char   set right  right  1  amp  amp  goto split once done         if   right  0 1   neq   delimiter char   set left  left  right  0 1          if   right  0 1   neq   delimiter char   set right  right  1          if   right   equ    goto split once done     goto split once loop       split once done     endlocal  amp  set   3  left  amp  set   4  right  goto eof
