Using logical processing 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 [, charspec1 [, charspec2 [,...]]]) Options 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 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. 3-6 Using LCDS Print Description Language
