Error: Undefined GLOBAL label

[ardentcrest]

Looking over an old file of mine that once worked I'm now getting Error: Undefined GLOBAL label . each one is going to a fastcall.

ie

        ld hl, lineMSG
        ld bc, end1-lineMSG
        call myPrint42

calling 

SUB fastcall myPrint42()
ASM
myPrint42:
    push    af
    push    ix
    push    hl
    ld    ix, PRINT42
    CALL    IXCALL
    pop    hl
    pop    ix
    pop    af
    ret
END ASM
END SUB

gives me Error: Undefined GLOBAL label ".myPrint42"

any help please....
