hello, good day.

I want to buy "the spectrum" at the age of 76.
I come from Germany.
I'm currently playing with the fuse and the zxbasic.
This zxbasic is wonderful.

I also play with the asm from the zxbasic.
I now want to learn how to use the system routines of the spectrum 48k with the zxbasic-asm.

Where can I find a system listing for the spectrum 48k?

thanks.
Best wishes

My program works when compiled in version 116 but does not work when compiled in version 117.

Example:
- select 3 discs.
- move from 1 to 3
- move from 3 to 1

It gives an error in the last version.

Permission denied on new installation.

And now, what do I do to resolve this?

In my program I had

DIM EDLINE AS STRING ' global variable

and if I wrote

EDLINE = EDLINE( TO LEN EDLINE-2)

then the test

EDLINE = ""

it didn't always work

and I had to use

LEN EDLINE = 0


Then I changed it to

aux = EDLINE( TO LEN EDLINE-2)
EDLINE = aux

and the test

EDLINE = ""

worked well.

When you press "1" the loop ends every second.

DIM s AS STRING
s = ""
PRINT LEN s-1 ' gives 65535
PRINT LEN ""-1 ' gives -1

Hi! I'm writing a game about a pig that has to eat various food items. Food items are realized by means of UDG's stored in DATA lines and READ in en masse at the beginning of the game. Then, to draw the necessary items, I move address 23675/-76 to the required location. Until yesterday, the system worked flawlessly. Now I added a new item, and the compiler began to throw the following errors. The highest address an UDG byte is stored is 65294, i.e. AFAIK it is still allowed. I did nothing else than add the new DATA files and jump conditions to draw the new item, and what previously worked impeccably, just stopped doing so. I simply don't know what to do. Could you help? Thanks in advance!

My program gives intermittent errors.
The result also depends on the emulator.
What's going on here?
Program error? Is the compiler broken?


files: files.zip

Is it possible to use assembler includes in the inline ASM code blocks
so the assembler can be broken down into files, e.g.

INCLUDE maths.asm

Also is it possible to include binary files in the assembler e.g.

BINARY 'test.bin'

Thanks
