Hi pjw, Try this : place lines 1 to 5, at 20 onwards. insert line 17 stop type goto 20, then RUN. Your program will run faster, because the interpreter does not have to search through the program to find what line it is on. The longer the program, the faster a piece of code to be timed will be run, ...

Hi Emmbee, Sorrry I was not too explicit : WHEN ERRor= errnum Was shorthand to remind you to look up the list of error numbers in the beginners guide, to adapt to any errnum reported in #0. You can do some wonderful things this way under QDOS: (not on QPC2). 10 When error=17: list#2, erlin-10 to erl...

Hi Emmbee,
You can even stipulate WHEN ERRor = errnum to cater only for a particular condition.

Hi Mark,
This is using two different disk drives. But the strange thing is that some floppies will read on either or both drives, but not all... All floppies are HD, and the problem is the same whether formatted QDOS or MSDOS!
Thanks.
Steve.

Hi Rich,
I can write to floppies on both systems and read them. It is just that what is written on one system can't be read on the other, altough not in all cases!

Errata :
Concerning the previous post, the Ql was only running with the SGC, without SMSQ/E being loaded.

More on floppies : I have an sgc_QL under SMSQ/E and a QPC2_PC. I formatted a floppy and copied a program onto it on the QL. Dir lrun etc work fine. Back on QPC dir flp1_ shows an empty disk! So I copied another program onto the same floppy using QPC. Dir lrun etc work fine for that program. back on...

Yes, we must be very careful with names : 100 PRINT 1 110 Define Procedure dummy 120 LOCAL PRINT(1) 130 PRINT(1)=2 140 PRINT 1 150 END DEFine Try this in on a QL! Briefly, Local names can use any global name in the name table. This could be used within a program , for example, to disable printed oup...

Thanks everyone. Now I can clearly see what needs doing. So work on the TSP will definitely proceed, as it looks like it already has quite good performance, running on a 2.8+ Ghz PC under QPC2. But that will have to wait until mid-january, as I am in the meantime fully occupied with other things. So...

Felt Pads for microdrives? Sounds like I could do with a hundred or so... if that would help resurrect loads of tapes at present inaccessible?
