The optional "REC=num-expr" clause is used to position the pointer to a specified record number before reading. After the numeric expression (usually a simple numeric variable or constant) is evaluated and rounded to an integer, the system reads that record number. If "REC = num-expr" is not specified, the system sequentially reads the next active record.
