I was able to use Joey s Answer to create a function  Use it as   echo off SETLOCAL ENABLEDELAYEDEXPANSION  SET  quot MYTEXT jump over the chair quot  echo  MYTEXT  call ReplaceText  quot  MYTEXT  quot  chair table RESULT echo  RESULT   GOTO EOF  And these Functions to the bottom of your Batch File   FUNCTIONS  REM FUNCTIONS AREA GOTO EOF EXIT  B   ReplaceText   Replace Text In String   USE     CALL ReplaceText  quot  OrginalText  quot  OldWordToReplace NewWordToUse  Result   Example   SET  quot MYTEXT jump over the chair quot      echo  MYTEXT      call ReplaceText  quot  MYTEXT  quot  chair table RESULT     echo  RESULT        Remember to use the  quot   on the input text  but NOT on the Output text     The Following is Wrong   quot  MYTEXT  quot   chair   table   RESULT       Because it has a   around the chair table and RESULT    Remember to add quotes  quot  quot  around the MYTEXT Variable when calling     If you don t add quotes  it won t treat it as a single string    set  quot OrginalText   1 quot  set  quot OldWord   2 quot  set  quot NewWord   3 quot  call set OrginalText   OrginalText  OldWord   NewWord    SET  4  OrginalText  GOTO EOF  And remember you MUST add  quot SETLOCAL ENABLEDELAYEDEXPANSION quot  to the top of your batch file or else none of this will work properly  SETLOCAL ENABLEDELAYEDEXPANSION  REM   Remember to add this to the top of your batch file

You can use    but you must have the ENABLEDELAYEDEXPANSION switch set   setlocal ENABLEDELAYEDEXPANSION set word table set str  jump over the chair  set str  str chair  word

You can use the following little trick   set word table set str  jump over the chair  call set str   str chair  word    echo  str    The call there causes another layer of variable expansion  making it necessary to quote the original   signs but it all works out in the end
