Syntax: For /L %% variable in (Start#,Step#,End#) do Command [Command Parameter] Example: @echo off For /L %%A in (0,4,20) do echo %%A In this command, we specified a start value of 0, a step value of 4, and an end value of 20. When this command is executed, the %%A variable takes the values of 0, 4, 8, 12, 16, and 20, and the Echo command is executed for each of these values. OutPut: 0 4 8 12 16 20

EXIT COMMAND Purpose: Quits the CMD.EXE program (command interpreter) or the current batch script. Note: Exit is an internal command if it is executed outside the batch file it close CMD.EXE Syntax: EXIT [/B] [exitCode] Prameters:   /B                specifies to exit the current batch script instead of  CMD.EXE.  If executed from outside a batch script, it  will                            quit CMD.EXE exitCode  specifies a numeric number. if /B is specified, sets  ERRORLEVEL that number. If quitting CMD.EXE, sets the                        process  exit code with that number.

Command Commands Used In Batch File Command Description Call Used to call one batch file from within another batch file without stopping the processing of the original batch file.
