Hi guys

is it possible to to concat EQU const with label? I have the code where I define _struct_name_internal_ as EQU and then I try to concatenate it to make a label. Here it is:

Code:

macro BEGIN_STRUCT struc_name  
{
  _struct_name_internal_ EQU struc_name   
  _struct_name_internal_#_begin:
  db 1, 1, 1
}

macro END_STRUCT  
{
  db 2, 2, 2
  _struct_name_internal_#_end:
  restore _struct_name_internal_
}

BEGIN_STRUCT my1
END_STRUCT

The problem is that compiler does not treat _struct_name_internal_ as my1, it leaves it as is (_struct_name_internal_)

comliped to:

Code:

_struct_name_internal__begin:
db 1, 1, 1, 2, 2, 2
_struct_name_internal__end:

instead of expected

Code:

my1_begin:
db 1, 1, 1, 2, 2, 2
my1_end:

cause I don't want to pass struct name twice into closing section Rolling Eyes

so if I define two structures, I get an error "ERR already defined _struct_name_internal__begin:"

Code:

BEGIN_STRUCT my1 
END_STRUCT

BEGIN_STRUCT my2
END_STRUCT

thanks in advance

You need to use match to translate EUQs in the preprocessor:

Code:

match x,equated_symbol { x#_stuff:}

*SOLVED* I'm happy =)) corrected code looks like this, thanks for help Wink

Code:

macro BEGIN_STRUCT structname
{
  structnameinternal EQU structname
  match x, structname  \{  x\#_begin:  \}
  db 1
} 

macro END_STRUCT   
{ 
  db 2
  match x, structnameinternal  \{  x\#_end:  \}
  restore structnameinternal
}
