I am a AVR “newbee”, maybe a stupid question, but I have been looking through “STUDIO 4” for a switch to set that will enable source code to be printed with line numbers!
In my last life, I used an Motorola 68HC11 ImageCraft compiler running in DOS, and it was nice to generate a “source code” print-out that did include line numbers.
All the AVR (red dot) error flags generated by “build” are linked to the source file and a line number. Counting down to line 254, for example, is hopeless. Maybe my only option is to tape pages together and measure with a tape calibrated in lines/page.
Forty years ago, I wrote machine code on fan-folded paper and measured relative branches with a 256 line tape numbered in hex from 00 to FF. The good old days before compilers!
