I have a tip, but I want to See screen.
Can you share the source?

At the moment I am using the line 1 REM statement to hold my code so I assume (never assume, I know) that as I am placing it there it must be quantity? My .p file is over 950 bytes now on a 1k zeddy. So your code is running in general, just too much code ? Your first statement did sound like it cra...

I now need to move over to using this process as I have just run out of memory! Or at least I assume so - when I add any new instruction anywhere it just hangs now and works again as soon as I remove the additional code. Lardo Share your not working code to what goes wrong. My computer is off at th...

I have modified the original ZX81.txt file so that it now assembles with TASM (using the zxasm.bat file from the hello world sample) and produces the same result as dr beep's file testlow.p zx81.asm I now need to move over to using this process as I have just run out of memory! Or at least I assume...

Yes, or here the full program in the compiler.

I use ZX Spin and export the binary with
File, Save binary file, and then address and lenght save as.P and load into EightyOne emulator

A base for coding in lowres. ZX81.TXT And the executable of it. testlow.P What do you use to assemble the ZX81.txt file? I am currently using TASM set up as per the example from the hello world example. Well you got the printout of the (altered) source from TORNADO assembler. TORNADO is an assemble...

A base for coding in lowres. And the executable of it.

When your source starts with the sysvars you can set them in a way that you can make better start of the code and better use of memory.

I can make an example program to use for further development as a base to start.

The problem with this "HELLO WORLD" example is possibly that the screen is full and not compressed.

Since 1K isn't that much you better define the size of the visible screen before starting coding.
So what is the idea of the game?

As for starting machinecode only,
You can set the start of machinecode and setting of SP, single use only, on the screen and do a clear screen in the game.
I do it all the time and save another few bytes.
