I have a big linked list consisting of a small header, a pointer to the previous item, and an included file. Kind of like this:

Code:

dd 0
__item1: include 'item1'
dd __item1
__item2: include 'item2'
dd __item2
__item3: include 'item3'

I'm trying to figure out a better way to link them, preferably using some sort of anonymous labels, which won't work because those included files could use them as well. I don't suppose there is some way to use labels local to that file only or something along those lines?

Could you use a macros similar to this do create the linked list?

Code:

prev_link equ 0

macro chain a, b {
 local c
 label c
 dd prev_link
 label a
 include b
 prev_link equ c
}

; Here's how it is used:
chain __a, 'apples'
chain __b, 'bananas'
chain __c, 'carrots'

This won't solve the label issue though; perhaps you could append a line of text specific to each file to the label (not sure how this would be done...)

Wouldn't something like this be enough?

Code:

macro linked [filename]
 { common local previous
     previous = 0
   forward
     dd previous
     previous = $
     include filename }

linked 'item1','item2','item3'
