7800basic issue - anyone seen this before?

+saxmeister · October 1, 2022

I was working on some code and started getting a weird error I had never seen before. So I started digging into the code and trying to squash any bugs I may have inadvertently added and had no luck.

So I scaled back the code cutting out chunks and testing with the same results. Then I pared it down to this bit of code:

  displaymode 160A
  set zoneheight 16
  BACKGRND=$08

__Main

  clearscreen
  drawscreen

  goto __Main

And guess what? This produced the same error. So I am thinking something is wrong with my 7800basic installation in VSCode on Ubuntu,

The console:

So this tells me that the code is compiling correctly and that the A7800 emulator has an issue, whether it's in the compiled code or the emulator is crashing.

Has anyone else had this happen? Any fix for it?

I have rolled back to older versions of 7800basic Studio and am having the same results there. And when I reinstalled the latest version and restarted VSCode I was still unable to successfully run anything.

Thanks!
