Well no-one else seems to solved this problem, so here's a solution.
The problem is to avoid multiple scanning of files acquired by GET,
similar to the multiple include problem in C. Objasm and AAsm have an
operator :DEF: for seeing if variables are defined yet. Thus one can
write:-

 [ :LNOT:(:DEF:A)
 GBLA A
;
; A is actually a variable whose name should be unique to this source
; file
;
; Insert your source here
;
 ]
 END

PS This may well be using an undocumented feature, it's a long time
since I wrote the code to implement it. and even longer since I've
seen the released documentation.
