Using logical processing Masked comparisons using nondefault type assignments Performing masked comparisons using either a nonstandard character set or a standard set for which the default type assignments are not suitable requires coding the following: • TCODE command: This command is used either to modify a set of standard default type assignments or to define a completely new set (shown in processing sequence 3 in the following figure). • TCODE parameter of the VOLUME command: This parameter is used to specify the set of assignments defined by the TCODE command as the one used for masked comparison. • The MASK and CONSTANT parameters of one or more occurrences of the TABLE command: The use of these parameters is the same as for comparisons using unmodified defaults, explained in the previous section.
