ASM features EQU and DEFM - LCD - 2011-11-01

Hi Boriel. I just adapted a ASM routine for key-redefining from WOS Forum to ZXBC for my next game, and noticed following:
EQU is not supported?
DEFM supports only Strings, but not mixed bytes+strings in one line like: DEFM 14,10,5,"Down",255
I adapted the lines by lacerating them to DEFB,DEFM and DEFB again, but maybe it would be a good idea to support bytes and Strings with DEFM, like other assemblers do.

EQU is supported. It should be used this way (if I recall correctly).

Code:
Asm

Label EQU 5 * OtherLabel  + 3 ; Complex expressions allowed

End Asm

Ok, I will try to add that in 1.2.9

I had problems with the code from here:

Code:
asm

; ---------------------- CONST -------------------

#line 3

BORDCR:

            EQU 23624

ATTR_P:

            EQU 23693

ROM_CLS:

        EQU 3435

CHAN_OPEN:

        EQU 5633

CC_INK:

            EQU 16

CC_PAPER:

        EQU 17

CC_AT:

            EQU 22

CC_OVER:

            EQU 21

end asm

This rsults in "Unexpected token 'EQU' [EQU]". Maybe a bug?

Re: ASM features EQU and DEFM - boriel - 2011-11-01

ZXasm does not support that syntax:

Code:
LABEL:

   EQU XXXXX

LABEL2:

   EQU YYYYY

Use this instead:

Code:
LABEL EQU XXXXX

LABEL2 EQU YYYYY

I understand, OK. Big thanks!
