That is, when you attempt to load (READP) or save (WRTP) a program, the 41 searches for the file (to be loaded) or for a place (for a file to be saved) on each mass storage unit, starting from the address defined by SELECT.

So very true… I was recently bitten by not understanding how SELECT works until (after an hour or so of frustration ) I read the manual J-F is referencing. What made it the more puzzling is that I was not using my real 41 at the time but V41, and it doesn’t show the error messages!
