(Free42) tips & tricks: local flags

[rprosperi]

Thanks Thomas, the ability to debug with flag-21 set either way is a reasonable premise, but it seems a stretch...

Some relevant and interesting notes:

The 82160A HP-IL module manual states that the 'TRACE with stack' option is not available in the 82162A printer. I only recall seeing this on a ThinkJet, guess that's why. (HP probably concluded supporting this would kill the 82162A batteries pretty quickly)

The 82242A manual does not mention 'TRACE with stack' option at all, and it says clearly that 'TRACE mode' is selected when flag-15 is set, with flag-16 either set or cleared.

It also states: "When flag 21 is clear, execution of printing functions in a program is suppressed." It also notes that flag-21 does not affect print functions executed from the keyboard, only print functions contained in a program.
