[Ql-Users] Wasted evening?
Sigh! Last night, I was doing some work on the next exciting article in the Pointer Environment series of Assembly programming for Ql Today. Basically, in the application window hit routine, I was attempting to print out all the meaningful data about the registers when the routine is called. Try as I might, the keystroke in D2.B would not print, unless a special case of -1, 0, 1 or 2. I spent ages looking, tracing with JMON and so on, I could see the keycode in D2.B but it simply refused to print when copied to D1.B. I was using IO_SBYTE/IOB_SBYT to print the keycode. There were never any errors seen after printing the keystroke as the trap always returned with D0=0 and the Z flag set. Eventually, I gave up and decided to pen a help me email to the list. While doing exactly that, I typed in a bit of the code and suddenly realised that I was a pillock! I was calling trap #1 rather than trap #3 - instead of printing a byte to a channel, I was force removing a (thankfully non-existent) job! Duh!

Norman, It's an easy enough mistake - I am just glad that you were not entering the job ID for the editor task - now that would have been a confusing bug to track down!! -- Rich Mellor RWAP Services http://www.rwapsoftware.co.uk http://www.rwapservices.co.uk -- Try out our new site: http://sellmyretro.com ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

With the book being available on the Spanish QL Resources site, and with Malcolm Lear tidying up the scanned copy, it ought to become available eventually in searchable formats. An alternative is Rich Mellor's Superbasic Reference Guide, which is available as PDFs on a CD from the SellMyRetro site. I have got the paper copy, but find it too big and bulky. I have asked Jan Jones for permission to re-typeset or reprint the book and she is thinking about it. Hopefully she will say yes or offer lenient terms...
