I'm aware that I can interrupt a running batch file witch Crtl-C, and then continue the execution.

However, is it possible to execute a command in the batch file's cmd environment while the batch is paused?

For example, I might want to pause a running batch, change some variables it has SET previously, then continue the execution.

add lines with modifications (i.e. set new value to the variable) after pause and continue the batch –  jet Sep 2 '12 at 19:34
    
such a simple solution! :) unfortunately, can't select comment as answer –  vedran Sep 2 '12 at 22:01
    
@jet: How would one continue execution of the batch file where it left off (i.e. right after the pause command)? –  martineau Sep 3 '12 at 0:47

@martineau: before pause, put command.com for example... and then you know... exit and you are back to the batch, maybe there is a better way –  jet Sep 3 '12 at 1:04

This code will allow to execute arbitrary commands from within batch context: Put it a batch file and play with it.

@echo off

:loop 
  set cmd=
  set /p "cmd=Please give command, empty line to finish "
  if defined cmd (
    call %cmd%
    goto loop
  )

To finish executing commands just hit Enter

To use it in your batch, just insert a line with call to above:

do stuff 
do more stuff

call interrupt_me.bat

do even more stuff

If you wonder why there is a call %cmd% instead of straight %cmd% - it allows to expand variables passed so commands like echo %comspec% work properly.
