CONSTANT
parameter syntax
example
The following CRITERIA command syntax diagram describes a
test for a subfield equal to a specific constant table.
criid: CRITERIA CONSTANT=(offset, length, EQ, tabid);
In the above syntax, the CONSTANT parameter specifies that
the content of a record is to be compared to the values that were
specified in a TABLE command with identifier tabid. Refer to the
“TABLE command” section in this chapter for an explanation of
the tabid parameter.
The subfield that will be compared is located the number of bytes
indicated by the offset variable from the start of the user portion
of the record. The subfield has a length the number of bytes
indicated in the length variable. When the subfield in the record
matches a constant in the table, the CRITERIA command is
TRUE and the processing specified by the parameter is
completed or acted upon.
CRITERIA LINENUM
Specifies the range of consecutive line numbers for which the
CRITERIA command is fully evaluated.
Syntax CRITERIA LINENUM = (init, count)
