The Sinclair QL Forum

I think for MDV's it would be simpler to just create a small mold and create the parts that way. Doing molds isn't that difficult, just requires a bit of hand labor. I had planned to create a mold of the QL case (bought top and bottom on eBay for that purpose) but COVID has interrupted that since I ...

I recently recovered software for my ZX81 that I bought in 1985. It was labeled a TS1000 Speech Synthesizer though in reality it just had 273 words digitized (over 9 libraries at about 500 bytes per word). Today I was able to recover the BioTalk program...after years of sitting in a box, the first p...

I found this resource from the Council on Library & Information Resources (CLIR) useful for magnetic tape information:

Especially this subsection on what can go wrong:

What year did the Miracle System Gold Card first come out? It's not stated on the QL Wiki.

By 'grammar' I suspect you all mean syntax 'railway line' graphs, as defined for example in Jan Jones' handbook. I tend to use Backus Naur Form (BNF) to specify a grammar though it's an old format that may not be as common as the inline mechanism used by lex/yacc, antlr and the like. Syntax diagram...

A well formed grammar isn't hard to write ... I beg to differ, slightly. But then gain, I'm not a compiler writer, nor do I play one on TV. ;) I dabble with ANTLR4 though. I suppose my statement was a bit sweeping. For many languages, writing a well-formed grammar is pretty straight forward. For a ...

As someone who has written interpreters, it's not always convenient to catch every syntactic (or semantic error) especially if done on a resource limited platform (i.e. 128K machine with 90K'ish of free RAM). I know in my ZXSimulator there are cases where something will work that shouldn't. I think ...

Maybe I'm just weird (don't all agree at once!) Or maybe because I used other programming languages, but using a repeat loop name which corresponds to another variable name seems a little daft to me? Happy to discuss if you think otherwise though. I might learn something new. That's what I was tryi...

I'm not a proficient SuperBASIC user but it's an odd example. I look at "loop" in your example as the REPEAT identifier and not a variable that I would assign anything to or use. So to me it's not like "FOR i=1 TO 10" where you then say "NEXT i" since that syntax asks t...

I was just asking for the sake of the QL-VGA card...so it sounds like in F1 mode for JSU you get the full screen.
