MAINFRAME - TIP OF THE DAY : When you use COUNT operator to set a return code of 12 or 4 if a specified data set is EMPTY, NOTEMPTY, HIGHER(n), LOWER(n), EQUAL(n) or NOTEQUAL(n). where n is a specified number of records. If you use the RC4 operand, SORT sets RC=4; otherwise it sets RC=12. E.g. COUNT FROM(IN) EMPTY

Why occurs clause cannot be declared at 01 level?

a table item is addressed
Quote:
as a displacement from the beginning of the table


according to the manual, a table is defined within a group item with an occurs clause.
if the occurs clause were to be declared at the 01 level, there would be no group item,
thus no beginning of table resolution.

01 represents a logical record. Occurs clause is used to repeat fields with same format, not the records.
