TABLE MASK
parameter: points
to note
•
Any valid character in the data character set, such as ASCII
and EBCDIC, may be used in the MASK parameter as a
mask character.
•
Any character that is not explicitly tested for absolute equality
by a TABLE command may be defined by the table MASK
parameter as a mask character.
•
MASK parameter character definitions apply only to the
TABLE command in which the definition occurs. As in
unmasked comparisons, it is possible to specify multiple
strings in the CONSTANT parameter.
•
To define a character specification use the form '
char
' or
('
char
', '
char
’, ...'
char
').
•
Mask characters should be defined using the same string
type as in the string specified in the CONSTANT parameter.
