Table 3-4. TABLE MASK parameter options and definitions

	Option	Definition
	ignorechar	Specifies a character that appears in positions that will not be compared, within
		a string constant.
	charspeci	character specification
		Specifies a character that appears in positions within a string constant where a
		test for type i characters will be performed.
	Default	No default
TABLE MASK		• Any valid character in the data character set, such as ASCII
parameter: points		and EBCDIC, may be used in the MASK parameter as a
	to note	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.
