The Sinclair QL Forum

Hi, today I have somewhat of a tricky C problem: Up to now, I never saw a need to use the _mneed variable (which, to my understanding, hints the runtimes to the initial need for heap memory of the program) in one of my (many) C68 programs. I normally leave it at its default of 8k. (I must admit I ha...

Prospero Pascal. Definitely. It has the diadvantage that you have to load the compiler runtimes as a ROM file using EPROM_LOAD or LRESPR (or have the ROM in the ROM port on a BBQL), both for using the compiler and the generated programs. Metacomco Pascal (second best IMHO) uses a ROM as well, but wa...

Do you think it is worth updating Q68Menu?

Not for me, I'm not using it (Most of what I do has at least some assembly code in a project and C68menu doesn't support mixed-language makefiles).
I think everyone should learn to use plain "make" to build software

Derek,

the sources for C68menu (the program seems to be Q-Liberated SuperBASIC) are contained in

424fsrc2.zip

Which can be downloaded from Dave Walker's site here

What do you expect to happen with the „-v” switch?

Simply replace it with “-c”, and you should be fine.

PS: c68 works equally fine on basically every QDOS/SMSQ environment.

A tight loop that direcly polls the frame interrupt flag of the 8301 and also checks for keypresses seems to work perfecly. And the polling runs in a job? Yes. SV mode, Interrupts disabled, system variables moved away to free up the second screen, then a tight loop that busy-waits on both the frame...

No worries, Peter - The Q68 has better ways to cope with the pictures than the clumsy old QL

I have solved the problem now. Both the random crashes and most of the flickering is gone now. Instead of using the method of Dithvide (hooking the screen flip routine to the polling interrupt and waiting for a keypress outside) that I couldn't for the life of me get to run on SMSQ/E - albeit that s...

Evening! With regards to multi-platform, I have some good news and some bad news: Bad news: The games won't run on a plain QL with memory expansion. That platform is too slow. It takes about 5 minutes for the first text to appear, then another ~3 minutes to parse the commands. The 68008 is simply to...

Not that I would know.

The simplest thing to do is run a sprite viewer on QPC and use Windows Snipping tool to grab the image as png. That's what I do in case I need a .png.
