And from another sample I found searching on EDIT MASK ASSEMBLER INSTRUCTION
To simplify maintenance of the program, I like to "document" the
print masks by showing a character representation of the hex fields
used in the mask. I use a B to indicate a blank as the leading fill
character, a Z to indicate digit positions where leading zeroes will
be suppressed, and a 9 to indicate digit positions where leading
zeroes will not be suppressed. For example, I would document the
print masks which we have used thus far as:
MASK DC X'4020202020202020' BZZZZZZZ
MASK2 DC X'402020202020' BZZZZZ
MASK3 DC X'402020202120' BZZZZ9
MASK4 DC X'402021204B2020' BZZ9.99
MASK5 DC X'402021204B202060' BZZ9.99-
CR DC X'402021204B2020C3D9' BZZ9.99CR
DB DC X'402021204B2020C4C2' BZZ9.99DB
CHKA DC X'5C20206B2021204B2020' ***,**9.99
CHKB DC X'5C2021204B2020' ***9.99

Another method is to use an * Comment to show the mapping.
* B Z Z 9 . 9 9 -
MASK5 DC X'402021204B202060' BZZ9.99-
