If I need to edit the code,I either use Wordpad on a Windows machine or Mousepad on a linux machine.As long as you understand what needs to go where,it isn't difficult.My most recent case was where the post processor was trying to return to machine coordinates at the end of a sequence and return to an absolute zero that would have been outside the machine envelope.It was faster to cut those lines and return the machine manually than to move the job and re-compute.
