TABLE MASK
Defines mask characters used within string constants (specified
by CONSTANT parameter). Also indicates which characters
denote special type testing and what that type is.
Syntax ac: TABLE MASK = (ignorechar [, charspec
1
[, charspec
2
[,...]]])
Options
Default No default
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.
