Recommended way to give a proximity label to a placeholder

[anrikun]

Currently this is how I give a label to a placeholder (self-modifying code):

subroutine1
  ;
  ; Some code
  ;
myval = $+1 : ld a,0
  ;
  ; Some code
  ;
  ld hl,myval 
  inc (hl)
  ;
  ; Some code
  ;
  ret 

The problem is that myval here is not a proximity label but a global variable. I would like to give a proximity label to my placeholder.

Obviously I could do something like:

.myval ld a,0
;
ld hl,.myval+1

or

defb 0x3E ; Opcode for LD A,n
.myval defb 0
;
ld hl,.myval

But none of these solutions satisfies me.

Maybe there's a way to do what I want but I couldn't figure it out. Any idea?

you may use a proximity alias

ld a,0 : .myval equ $-1 ld hl,.myval

advantage is that you could use .myval before it's declared

Wow, great solution! Thank you for your help as always, Edouard.

Actually there are downsides to all solutions so far: Placeholder does not get a real label so it doesn't show up as a symbol when debugging with Winape. I end up with ld (#08AD),a instead of ld (.myval),a

I've found another workaround:

org $+1 : .myval : org $-1
ld a,0

Not very easy to read but it works...
