Re: Is SBASIC programming on SMSQE difficult?

tofro posted Nope, there's no such thing as hardware that stops and continues multitasking programs. The computer is simply interrupted every 20ms to check whether another job needs to run. If yes, the scheduler "simply" exchanges the CPU context of the currently running job with that of ...

Re: Is SBASIC programming on SMSQE difficult?

Martin head posted:- This could reduce the system load during a paused program. Seems like a good idea. Does reducing a job's priority actually do this? I assume that hardware is required to actually STOP and CONTINUE a program, but doesn't this kind of hardware exist on all computing systems? How ...

Re: Is SBASIC programming on SMSQE difficult?

I'm with Pjw on the matter of a hardware WAIT for SMSQE. Meanwhile I would like thank Martin_head for his Q68Wait instruction. Does the instruction actually halt the program or does it run a program loop reading the real-time clock?

Re: Is SBASIC programming on SMSQE difficult?

I understand the SLUG command as an instruction to slow the processor and not an individual application. Is this correct?

Re: Is SBASIC programming on SMSQE difficult?

I tried using PEEK_L($1C060) on a Q68 and in SMSQE's command line. It works as Peter describes, but I have two problems. The first is that Qliberator will not accept $1C060. I have read through the Qlib manual but can't find a reference to this problem. The second is that I cannot think of a way to ...

Re: Is SBASIC programming on SMSQE difficult?

Blimey, So much to think about. So much, in fact, that I am going to have to collate all the posts and print them out. What, and/or where,and what is the purpose of the Q68 hardware timer. Could someone write some demo code to include the use of PEEK_L($1C060) as a method of controlling program flow...

Re: Is SBASIC programming on SMSQE difficult?

Thanks for all the replies. There is quite a lot to take in. Once I have grasped it all, I will be back with more thoughts and questions on programming and programming in Qlib BASIC. I have been slowly writing programs designed to test BASIC instructions, such that I can see what I can do with them....

Is SBASIC programming on SMSQE difficult?

The very short answer according to google is yes. I agree with this, whereas tofro and Norm do not. For some time I have been trying to learn to write programs in Qliberated BASIC on/in? SMSQE because as mk79 wrote "I actually like to do this stuff" or as he also wrote, its like doing &quo...

Are you willing or able to publish TF's designs and your designs together with the software necessary to drive them?

Re: QDesign source code

I meant hard, as in playing a musical instrument is hard. As you suggest, anyone can code but one is faced with an immediate problem when doing so. One needs to quickly cross a very high barrier (especially if one is not naturally talented) before it becomes enjoyable enough to carry on learning. Th...
