Line and Column Combinations

Certain combinations of line and column numbers have special meaning:
identifier-3, integer-2
Identifier-3 must be a PIC 9(4) or a PIC 9(6) field. Integer-2 must be a 4- or 6-byte numeric field.

If identifier-3 or integer-2 is 4 digits long, the first two digits specify the line, and the second two digits specify the column. If identifier-3 or integer-2 is 6 digits long, the first three digits specify the line, and the second three digits specify the column.

Identifier-3 cannot be a floating-point data item.
