The Sinclair QL Forum

Ta Ta Ta Ta I finally have found Computer One Monitor, but not Version 1 (its on Dilwyns page), but version 2 (Professional Monitor). I even have the printed manual. Unfortunately I haven't found the original disk, just the C1MON executeable - it runs on QPC2 :-) Advantage of Professional Monitor: S...

When trying to run some of my games on QPC I have found an incompatibility of SBASIC. I've tried to start Psion Chess from one of my old "Games Floppies". In the boot file there was a construct like this: ... DeFine PROCedure something DeFine PROCedure pat do something END DeFine PROCedure...

Using and learning SuperBASIC on the QL is just a bit more fun than on a lot of other 1980's computers Mark Well SuperBASIC was an excellent language of its time. But I must say (I love the QL),it's now a bit out dated compared to "the monthy PHYTON's flying circus". Python has as SuperBA...

When using functions which return a float, you often want to signal an error to the calling procedure. in C/C++ there exist NAN (or similar) which is no number, but can be returned. This can be interpreted as an error. In SBASIC such a value doesn't exist to my knowledge. So a good candidate would e...

You will find that information in the QPC Keywords manual. Basically you can just use the EX* command family to execute an SBasic job just like any other. From the manual: OK, I knew that it is possible to start Basic file as job with ex. But I didn't know that channels and command strings are pass...

How can a SBASIC job be started on QPC2? I don't mean the SBASIC keyword (btw it is very limited), because that is only available from SuperBASIC not from other languages. Is there something similar like Minervas "multib_exe", where it is possible to pass channels, CMD$, ... This was very ...

Hello Jan,

nice to see you here. I think we met once in Eindhoven (I think 1989 or so). I was a heavy user of your editor (delivered with C68), cause it was the one I used together with QLFED (the Maustausch program for the German Mausnet).

I think you are right. The assembler calculates the distance from the PC to the address - programmers are lazy and this saves 4 characters typing ;-)

Ok, So I'm trying to port the released QLSD source for use in my own hardware implementation. This will be on a standard expansion card and so i will need to put the I/O registers at a specified offset from the beginning of the ROM and **NOT** an absolute address. I just can't figure out how to do ...

At first I wanted to install pie_ext, PICE and NICE to get full multitasking (see this thread ). OK, it's not necessary any more (PE_BGON). Unfortunately these commands seems not to be documented (at least not in the Keywords document of Marcel's QPC-Web-site). Are there any documents, to get all th...
