Music is 6 channel dual AY music, a cover of Madonna's Hung Up by Factor6.

It uses Putchars by Britlion, then everything else is written in ZXB (the vumeters are done with inline ASM)

  PRINTAT64(0,0) not working on zxbasic-1.4.0s1995 (*solved*)
Posted by: Luzie - 2017-04-23, 02:11 AM - Forum: Bug Reports - Replies (16)

Hi,

i try this on zxbasic-1.4.0s1995:

Code:
PAPER 7
INK 0
BORDER 7
CLS

BORDER 1

#include <print64.bas>

LOP:
PRINTAT64(0,0)
PRINT64("Test1234")
GOTO LOP
But this prints "Test1234Test1234Test1234" and so on and not just in the upper right corner?

  sgn fails if the argument is a variable
Posted by: britlion - 2017-04-08, 05:18 PM - Forum: Bug Reports - Replies (2)

zxb version 1.4.0-s1980

Code:
dim y as uByte=1
print sgn y
print sgn 2

This wont compile. sgn <number> is fine. sgn variable isn't.


Code:
Traceback (most recent call last):
  File "zxb.py", line 348, in <module>
  File "zxb.py", line 274, in main
  File "ast_\ast.pyc", line 34, in visit
  File "arch\zx48k\translator.pyc", line 340, in visit_UNARY
api.errors.InvalidOperatorError: Invalid operator "SGN"
Build Failed!


Definitely a regression, as it worked fine with an older compiler!

  Help understand where things end up in memory
Posted by: emook - 2017-03-12, 06:02 PM - Forum: Help & Support - Replies (4)

Hello,

I've been using ZXBC for some projects I am doing, one of the things is that I working with very limited memory. I'm writing my code to start at 25000.

When I am doing an ASM include no matter where in the code I place it, there is still ZXBC code after.

If I place all my inlcudes at the end of my program, they still appear around 40-50 bytes in. I need to be able to tag the includes on at the end of the file, not in the middle as once I have moved them to another located they can be discarded but with ZXBC code appear AFTER the includes it means I keep running into trouble.

I know about ORG in ASM but I'd rather ZXBC obey me when I have a include as the last lines to see in memory that it also appears at the end of the code.

Any ideas?

A friend of mine is a graphic artist in the C64 demo scene from the Level64 group. Some weeks ago he wanted to experiment with ZX screen graphics and did this wonderful screen linked below. I added some small animation for the copkit with Boriel basic.
