Invalid picture strings

I have 2 picture strings that seems to be valid per the documentation (coming from ACUCOBOL), but the compiler is giving errors. Any ideas why these are invalid?

They are:

This one gives error saying "Incompatible qualifiers".

PACT-AMOUNT  PIC S9(9)V99  COMP-3
                 SIGN IS LEADING SEPARATE. 


This one gives error "PICTURE string has illegal precedence or illegal character"

 Disp-Comm-Pct                    PIC ZZZ.Z9.


Thanks
