HI

I know that i have variables unused on assembler functions

where I use assembler only and i grab the values for example like this LD E, (ix+8)

Is there any pragma or something to not show this on the compiler message?

because if i have a lot of assembler functions there are a lot of messy output on the compiler

with message like this : warning: Parameter 'parameterName' is never used

Can i hide this type of message when i know that is "unused" in a assembler function?

If i can hide this type of message is more easy to develop

i don't know something like

#thisFunction dontShowThisTypeOfMessage

I don't know if i explained myself

Thanks

Hi.

I see data from address $FF18 (65304) - $FFFF. 231 bytes. It seems to start with F3 0D CE 0B E3 50 CE 0B... I have not seen it change size or start address across a few programs.

What is this data? Does it remain constant / static?

Provided I keep my main program code < $C000 and I copy this reserved data from $FF18, into all 128K banks 1-7, will I be free to use 128K paging as I choose, loading data and / or binary code into each page at specific addresses?

Will the program need this reserved data in the other 128K pages or is it maybe only used during program initialisation?

Thanks!

Hi there,

I'm in need of some advice with loading code to specific addresses.


1. A way to include a ZXBC basic file - during compilation - at a specific address. Something like this...
#INCLUDE "font.bas" ' load font relevant code to 24576
#INCLUDE "setup.bas" ' load program setup code to 24576 + compiled size of font.bas
#INCLUDE "graphicscode.bas", 38000 ' load graphics code and variables direct to address 38000.

This would see non-speed critical #INCLUDE code (and variables) first compiled to the program's ORG address (24576) and code (and variables) that must run in uncontended memory space - placed at the specified address.


2. How to directly include a binary blob to a specific address, without the use of labels and memmove, memcopy, zx7 unpack, etc. Something like this...
ASM
INCBIN "graphics.bin", 45000
END ASM

Thanks

Hi

I'm trying this

DIM variableName( 20 * ( myVariable + 1 ) ) AS UBYTE

but the compiler says : "Array bounds muts be constants"

Is there any way to create a DIM with variables?

With a Basic variable?

Thanks

Hi

Well... this is the question

If I do a FUNCTION or SUB When is good to make it fastcall ?

how can i know if ist's better as a fastcall or not?

How can i know that?

Thanks

Hello!

I'm trying make scl2trd tool for esxDos.

I did:

Hi : ) I want to do something like this

iniSuperSub:
SUB mySuperSub()
....
...
....
END SUB
endSuperSub:

SUB otherSub()
ASM
defs 6144-(@endSuperSub - @iniSuperSub),0
END ASM
END SUB

The compiler says -> Error: illegal preprocessor character '@'

I want to do in assembler -> defs (6144 - size mySuperSub ), 0

There is some way to do something like this?

Thanks

Hi

THIS CODE WORKS AS EXPECTED

1) CLS
2) Print "Hello"
3) Make a sound with assembler subroutine
4) Print "World"
5) Make the STOP

--------INI CODE ---------------------------------------------------------------------------------------------

SUB mySound()
ASM
LD B,5
loop:
PUSH BC
LD HL,768
anotherLoop:
LD DE,1
PUSH HL
CALL 949 ;'ROM BEEPER ROUTINE 949 = $3B5
POP HL
LD DE,16
AND A
SBC HL,DE
JR NZ, anotherLoop
POP BC
DJNZ loop
RET
END ASM
END SUB

CLS : REM 'Clear screen

PRINT "Hello" : REM 'Print Hello on screen

mySound() : REM 'Make the sound

PRINT "World" : REM 'Print World on screen

STOP : REM STOP the program

----------------- END CODE ----------------------------------------------------------------------------------------------------

But if i change something, doesn't work

Per example :

1) ¿BUG ERROR?
If i change the assembler code and i put PUSH IX AT THE BEGINNING AND POP IX AT THE END
that is the advice in this forum to all assembler routines

SUB mySound()
ASM
PUSH IX ; This make the program not work properly
LD B,5
......
......
......
DJNZ loop
POP IX ; This make the program not work properly
RET
END ASM
END SUB

doesn't work


2) ¿BUG ERROR?
If i add some blank space to the words printed per example "hello " blank space at the end or somewhere
or at the printed word "world " make the program not work properly and don't execute the last print and the stop

3) ¿BUG ERROR?
If i add ; at the end of the word "Hello" per example "Hello"; doesn't work either

4) ¿BUG ERROR?
If i make the words "Hello" and "World" variables Per example a$ = "Hello", b$ = "World"
anfd i make

PRINT a$ : REM 'Print Hello on screen

mySound() : REM 'Make the sound

PRINT b$ : REM 'Print World on screen

doesn't work either


-----------------------------------------------------------------------------------------------------------------

I don't know what is going on ¿?¿?¿

Thanks

Hello Boriel,
I found a problem wih bright 8
I'm coding some routines for a game and I need use bright 8 to draw four lines on a square with attributes: ink 2 and bright 1
I set paper 8, ink 8 and bright 8 to draw lines in this zone but zxbasic changes the brightness to zero and seems doesn't works.

Thanks
