How redirect PRINT to the printer? how makes LPRINT?

HI

Is possible redirect the output of the PRINT to the printer ?

Something like
PRINT #3; "This go to the printer"
that print on the printer

or something like
OPEN #4, "p"
that redirects the channel four to the printer and after this we can do

PRINT #4; "This go to the printer"

Is there some "easy way" to do that with the ZX basic ?

Maybe there are some library that makes the LPRINT of the ZX spectrum

Thanks

Hi,

I have proved an old program from the ZX Spectrum Basic to Boriel's Basic.
Some 700 lines of code.
The program can compile now and it is running on a Spectrum emulator.

However I get an error "3 Subscript wrong, 30:1"
wich is a very generic error coming from the "RANDOMIZE USR 32768".

Is there any way to tell where the error occurred in my source file?

Here is what I used for compilation:

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
