Hello,

The documentation for CHR function (https://zxbasic.readthedocs.io/en/latest/chr/) says that, although expanded, the function is 100% Sinclair basic compatible.
If it is so, then for the same parameters I'd expect the same output, not only for ascii letters, but also for sinclair basic keywords.

In Sinclair basic, this programme:

Quote:..\..\zxbasic\zxbc.exe --optimize 2 --output zxkeywords.tzx --output-format tzx --BASIC --autorun --explicit --strict zxkeywords.bas

Hi!
Another bug or at least improvement, sorry!
When I create constants, such as:
const DCMD_EOD                            as ubyte = 100
const DCMD_LINE                           as ubyte = 101
const DCMD_CIRCLE                         as ubyte = 102
const DCMD_FILL                           as ubyte = 103
const DCMD_UDG                            as ubyte = 104

And then try to use them like so (initializer expression):
sub draw_presentation()
    dim pic_data(11) as ubyte => { _
        DCMD_Circle, 50, 180, 10,  _
        DCMD_Fill, 50, 180,        _
        DCMD_Circle, 100, 160, 25, _
        DCMD_EOD }
   
    draw_pic( pic_data )
end sub

Or maybe like so (DATAs):
LocPics:
    ' Loc 0 - Limbo
    data DCMD_Line, 0, 180, 250, 100, _
        DCMD_Line, 250, 180, 0, 100, _
        DCMD_EOD

    ' Loc 1 - Landing
    data DCMD_Circle, 50, 180, 10,  _
        DCMD_Fill, 50, 180,        _
        DCMD_Circle, 100, 160, 25,  _
        DCMD_EOD

I receive the following errors:
For the use of constants inside DATAs:
locs.bas:64: warning: [W100] Using default implicit type 'float' for 'DCMD_Line'
locs.bas:69: warning: [W100] Using default implicit type 'float' for 'DCMD_Circle'
locs.bas:70: warning: [W100] Using default implicit type 'float' for 'DCMD_Fill'

This doesn't make any sense, since they are defined as constants of type ubyte.
For the use of these constants inside the constant initializer for an array:
reveni.bas:14: error: Initializer expression is not constant.
reveni.bas:19: warning: [W100] Using default implicit type 'float' for 'pic_data'
reveni.bas:19: error: Invalid argument 'pic_data'

Again, this doesn't make any sense, since they are constants but the initializer expression is erroneously detected as non-constant.
Could this be solved?
Thanks,

Hey I just tried to download (from all the links) and got nothing.  Links look good but boriel.com/files appears to be empty.  Is that right?  It's Sunday night so maybe it's maintenance?

Thanks - Dallas

I've been enjoying using ZX BASIC so far. It's great to have something that's easy to use (and in-keeping with the original Sinclair BASIC). I have come up against an issue which I can't find a solution for:

The compiler supports multi-dimensional arrays, but it throws an error if I attempt to get a "slice" of the data.

My code:

Quote:
array_test.bas:9: error: Syntax Error. Unexpected token '(' <LP>

Out of simple routine, I created a for loop like this:

There's no function or command "fill", allowing to pass two coordinates and making the computer to fill all delimited pixels with the current color.

hello, good day.

zxbasic:
put small ASM programs like bin in a bank(1,3,4,6)  from spectrum 128 and then call them from basic in the $c000 ?


how does that work please?



thanks.

Hello,
I'm trying to code a simple headerless LOAD routine in ZX Basic using the inline assembly feature of the compiler. The basic idea here is to write a function that uses assembly to set up the necessary registers and call the ROM routine 0556h for a headerless load (e.g. to load an extra level from the tape). I have some progress in this area, but it looks like I misunderstand how to clean up things correctly after the ROM routine returns and my function ends, so the poor Speccy either hangs or is reset after the code loading routine completes. I tried a few things so far, but the experiment that went the farthest so far is this one:

Is it possible to turn off the Keyword hints in ZXBasicStudio ?

I can't see them in the dropdown popup, and it annoyingly makes entering code awkward.

I had an issue with my Boriel that prevented me from using the debugger. This has been fixed with help from the forum and me installing the latest version of the Boriel ZXBasicStudio.

My issue now is that I can no longer see Key Words when entering code (see attachment). If anyone could help on this it would be highly appreciated.

I checked with the older version and that does show the KeyWords, but won't run in debug mode.
