OK, to make this work, I commented out lines 411 and 412:

; if (psym[I] eq 8) and (N_elements(usersym) GT 1) then $
; usersym,usersym,fill=fill,color=colors[I]

This means you won't be able to specify your own symbol in
legend anymore. (Why would you need to if you are using
SYMCAT!?)

Then, on line 422 I found the PSYM keyword and changed
it from "psym=psym[I]" to "psym=SYMCAT(psym[I])".

Done.

Then, I tried this:

IDL> items = ['Filled Square', 'Hourglass', 'Filled Star']
IDL> sym = [15, 21, 46]
IDL> Legend, items, PSYM=sym

For a quick and dirty solution, it's not so bad. :-)

Cheers,

David
