i have a macro to build a linked list:

Code:

macro PROSECT [_label,_name] {
;------------------------------
local ..next
;------------------------------
forward
            dd 0
            dd ..next ; "next" pointer
    #_label db _name,0 
    ..next:
;------------------------------
}

i would like to detect last iteration and place zero into "next pointer" field instead of ..next value - is there short correct way to do this?

thanks!

This one should work in your case:

Code:

macro PROSECT [_label,_name] {
;-- ----------------------------
forward
    @@:
            dd 0
            dd @f ; "next" pointer
    #_label db _name,0
common
    @@ = 0
}

Won't that redefine @@ where the macro is used?
I mean:

Code:

dd @F

PROSECT abc,abc,def,def

@@: db moredata
