Re: [Vb81] Disassembler Window
If not too hard would it be possible to make the disassembler window resizable? I find it a bit constricting, especially when the contents of the registers are being shown. I'd also like to see wider columns, these are sizable, but restricted because of the size of the main window. Just a suggestion...

ZX81 Academic and Research related articles!
https://www.tandfonline.com/action/doSearch?AllField=zx81 Most of these are "Locked", so you can only read the abstracts, which gives you the idea. You can pay to get access if you want. A few are "Open Access", like the Quicksilva article I posted yesterday. Here's another one https://www.tandfonli...

Quicksilva article
Hope this hasn't been posted before, the article was uploaded in 2016, so it's pretty new.

Re: Machine Language help
Using the ROMs find line address routine at 09D8 LINE-ADDR. may work better. or not, for your REM loop. For a given BASIC line number this subroutine will return the starting address of the actual line or the starting address of the following line if it does not exist (C reset). 09D8 LINE-ADDR PUSH ...

Re: [Vb81] Text Compiler Bug
This line...
10 LET X=16623
Produces a false error message!
This line...
10 LET X=Val "16623"
Avoids the error message.
I've seen this bug before with other values as well, weird huh.
See the attached.

Re: Hello from Nottingham, UK.
High Rise Hive is a HogRogProg game. See HogRogProg Collection in the games forum for more great games by them. I really like Bug Burst myself.

Re: ZXPand Organizer
I've updated the program with line... 9997 IF PEEK 49151>MAX THEN POKE 49151,0 Also the HogRogProg and Benham Disk programs. This should work as long as the VARS have been initialized before saving. BTW, what value do you get when you PEEK 49151? I guess the T/S1000 and ZX81 aren't 100% compatible! ...

Re: ZXPand Organizer
As noted elsewhere, the videos I posted where created on a REAL, repeat, REAL TS/1000 with ZXPand+ interface. I've not come across the problem so I didn't know there was one. Adding a POKE 49151,0 to the start-up would negate the reason its there. It's there so that if say you pick item 46 from a lo...
