Seems to work fine for me from my Machine Code routine in BASIC.

1020 DATA 01,CD,DE,BB,3E,E9,CD,5A
1030 DATA BB,C9,00,00,00,00,00,00




The assembly looks like this:

org &8000


ld a,&ff
call &bb63
ld hl,100
ex hl,de
ld hl,100
call &bbc0
ld a,1
call &bbde
ld a,233
call &bb5a
ret


In the past I've used GRA_WR_CHAR &BBFC, which draws the character (stored in A) at a graphical position, the only difference being the need to specify the character number for A. TXT_SET_GRAPHIC (&BB63) needs an input too, but only in the capacity of Switching Graphic Draw On/Off with a Non-Zero/Zero approach, which is what your code has and then print using TXT_OUTPUT.
So I'm unsure why it's not working, has Firmware being disabled perhaps? I guess if MODE isn't working that would be a clue or if the Screen wasn't clearing.

hello thanks.


this not funktion in the sdcc:
ex hl,de

I think it's meant to be
EX DE,HL

[AMSDOS]

It's a bad habit of mine because the Winape Assembler accepts either 'ex hl,de' or 'ex de,hl'.

Hi good afternoon.

tag-move-printc are not yet working together.
it doesn't work with sdcc.
is probably a peculiarity of sdcc.
the ascii is not moving.

thank you.

Sorry, I don't know sdcc all that well, have you tried it with the leading '0x', the first ld instruction follow by the call to bb63 has one, so perhaps to the others are necessary too?

It has to be more like this:

void Tag()
{

ld a,#0xFF
call #0xBB63

ex de,hl
ld hl,#100
call #0xBBC0
ld a,#1

ld a,#233
call #0xBB5A
__endasm;
}

EDIT: sorry, having issues with code tags in the forum editor!

Hi good afternoon.
I can not do it.
that's the program.

I got lost and can't get to my destination.

who knows about it in sdcc please.

thank you.

Well if 'ld hl,#100' is meant to be like that, then shouldn't 'ld a,#0xff' read as 'ld a,#ff'?

No, because #ff is a hex value, so needs to be #0xff.

[AMSDOS]

Though I was thinking that 'ld hl,#100' were also hex values because of the '#', which would place the graphical cursor at 256x256.

I was suggesting to test it like this in SDCC:

#include <stdio.h>


void main()
{
__asm
ld a,#1
call #0xBC0E
ld a,#0xFF
call #0xBB63
ld hl,#100
ex de,hl
ld hl,#100
call #0xBBC0
ld a,#1
call #0xBBDE
ld a,#233
call #0xBB5A
call #0xBB06
__endasm;
}



If that doesn't work (not changing to MODE 1 for example), then perhaps SDCC has disabled the Firmware?


I'm only able to test in your SDCC example you posted with Phrozen C, which works, but the output for letter 'A' is along the Bottom Left corner with 2 'A' behind one another (see screenshot).
