can,
Yes, that file is the driving script. The "R" command is a repeat command that causes the script to go backward N records and repeat M times. So there are many repeats at the high temperature and the experiment can easily go for 6 days. If I determine after a while at 1150C that the experiment is non-performing, I don't have to wait all 6 days, I can tell it to jump to the script command at the start of the cool-down sequence. Also, the "T" command is to test the cell for activity. The power supply is disabled until the temperature falls by N or M minutes are exceeded. Usually the last opcode is the pressure for the back pressure regulator (only limits the maximum pressure by leaking gas out).
I have run a number of experiments like this before where there were many manual changes in temperature and pressure. They were impossible to repeat manually - even to do a null calibration test. Because of that I was determined to have my experiments driven by a script so that I could repeat them.
