Passing array to procedure in BBC Basic(Z80)?

[Neurox66]

Hi,
I've a question:
Is passing an array to a procedure in BBC Basic(SDL) the same in BBC Basic(Z80)?
I am writing a program in BBC Basic(Z80) for Agon Light 2 but when I run the program it reports a laconic "Syntax error at line 50"
This is the example code:

Code: Select all

   10 DIM A%(20)
   20 FOR I%=0 TO 20
   30   A%(I%)=RND(50)
   40 NEXT I%
   50 PROC_SHOW(A%())
   60 END
  100 DEF PROC_SHOW(B%())
  110 SIZE%=DIM(B%(),1)
  120 FOR I%=0 TO SIZE%
  130   PRINT B%(I%)
  140 NEXT I%
  150 ENDPROC

It works with SDL but not on Z80.
Any hint?
Thanks,
Paolo

No, passing whole arrays to procedures and functions is something that was introduced only in the 32-bit versions of BBC BASIC, so that's ARM BASIC 5 and 6, BBC BASIC for Windows, BBC BASIC for SDL 2.0, the BBC BASIC Console Mode editions and the various varieties of Brandy. 8-bit and 16-bit versions of BBC BASIC don't have that capability; in those, arrays are always global.

We are spoilt by all the BASIC 5 (and later) extensions, and working with 6502 or Z80 BBC BASIC can sometimes feel a bit primitive!

Yes, you are right.
We have been spoiled

use the bbcbasic24 for the agon.
with the bbcbasic24 you can use the entire 512kb from the agon.
The buffer editing is great from bbcbasic24 (agon).

hello everyone, good day.
I'm 76 and I play with the "agon console8 emulator".
this forth24 is great for my hobby.

now I want to tinker around with a (screen) mode...
I haven't yet figured out how to set points in a graphic screen without this vdu.

how do you get the addresses to set your own colored points?

thanks.
best wishes

This appears to have nothing to do with Passing arrays to procedures, nor with BBC BASIC (Forth24 is a version of the Forth language).

BBC BASIC (Z80) version 5 supports passing entire arrays to procedures, and indeed nearly all of the other BASIC 5 extensions.
