I often use perldb within the Emacs editor to debug perl scripts. I can edit the perl code and, using the "R" command, re-run the script with the changes. However, I have not found a method for changing the perldb command line arguments and rerunning the script. I usually exit Emacs, restart Emacs, run perldb, reenter an often complicated, slightly modified script command line, reestablish any break points and run the script.
Is there any way, from within emacs, to modify the current perldb command line so as to enable rerunning one's script?
