I have had another go at modifying the QLib runtimes for the Q60 problems.


Hi Martin, I have good news this time. Programs such as QCoCo, ACP, EddIcon, My screen copier, and others that do not have older runtimes incorporated seem to run correctly, smsq/e 3.42 plus copyback ...

Answer : no its not a solution. Compiling with AUTOF set to off or patching AUTO to off fails to alter the behaviour of QLiberated programs with copyback.

The problem with FOR ...

Hi Martin,

On my Q60 a first quick look at Q60test01 runtimes was not good. Booting into smsq/e 3.41 cache in writethrough Launchpad fell over with error 35 index out of range. Qdock however was Ok. Testing Qcoco, ACP and SQRV form Qdock resulted in all failing with error 35. Launchpad - bodged ...

Hi Martin,

I have run your variable listing program on both the compiled versions on the sceen copy program, one with a FOR loop and one with a repeat loop. An integer variable of type $00 is present in both, so probably not the cause of copyback problems.

Now since the version of the screen copy ...

Martin wrote: Do you have AUTOF turned off in QLib

Generally speaking I compile with AUTOF turned on.
Since you first mentioned AUTOF I have recompiled the screen copier(FOR loop) with AUTOF turned OFF. And the resulting screen copy is similar with lines skipped and approximately halfway through ...

RalfR: wrote Interesting that the program started at all

I have a small number of QLIberated programs that run apparently OK with copyback. The screen copier was not one of them obviously.

Hi Martin,

Although your patch program did not work, here is something that indicates that FOR loop variables are at least part of the incompatibility of QLib with copyback. I have a small program to copy the screen to a pic file. The program does not copy the screen correctly when compiled and ...

Hi Martin,

Sadly the patched version of the qdock programs does not run on my Q60 with the copyback caches turned on. I have tried it with both smsq/e 3.41 and 3.42. THe errors it poduces are similar to the errors with the unpatched versions of qdock : varied QLib error messages, a locked window ...

Basically, QLib programs with Copyback cache enabled already run on the Q60. Programs that don't run (e.g. Q-Dock and Qtrans [this is just an example, as they are regurlarly used]) contain code from easyPTR. So it could be that the problem lies there. Possibly also in connection with ...

Hi Derek,

To predict the possible current level interest in Q60 boards are you able to say how many Q60 boards and systems D&D sold back in the day.
You have already stated that only one Q40i was sold.
I am only interested as I myself bought a Q60 back then, serial Q60-80-A6-003.

Cheers
