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.
