HU-BASIC Commands

Well, here they are!

Very useful as I don't think there is a European manual for HU-BASIC

Re: Text To Speech

Yes indeed. I'm sure the 'priming' is a big factor. I remember a VIC-20 demo where speech was created in the music but you wouldn't really be able to understand it unless you read the words which were also on the screen.

Re: S-BASIC Screen Scrolling

Yep, a waste of memory then which could be put to better use for more space for BASIC programs. Took me ages to work out that you could scroll the screen up with SHIFT - UP :D It surprised me though because I assumed the 700 didn't have the 2KB VRAM which the 80A has.

S-BASIC Screen Scrolling

Is S-BASIC really wasting precious memory keeping a copy of the screen so that you can scroll a BASIC listing back into view again when it's disappeared off the top of the screen? (Like the MZ-80A, except the 80A actually has 2KB of VRAM especially for this purpose).

Re: LD SP,????

Thanks. That's what I thought anyway. I didn't want to find myself overwriting anything that the Monitor would use the stack for. But I guess if you are resetting the SP to $10F0 like this then the Monitor routines won't change it at all and it'll all just be used correctly. At least, when just call...

LD SP,????

Hi,

Just wondered, when you're writing your assembly programs, is it acceptable to use LD SP,$10F0 ? i.e. use the Monitor's work area as a stack? Or should this be avoided?

Re: SA-5510 Disassembly

No, as I say, the instructions are to load BASIC SA-5510 first, then type in MON to get back to the Monitor and then you must load this 'loader' program. Just trying to transfer the software into MZF format but it's going to take a bit of work as there is no stored header on the tape (the loader pro...
