Occur clause is a kind of an array which holds the data of
simalar type in a particular record.
Ex: If we define an occur clause which hold the marks of a
particular student scored in 3 subjects. The code for this
would be as mentioned below

01 Student.
02 Name PIC X(20).
02 MARK OCCURS 3 times PIC 9(03).

So, For a Student "A" marks would be stored in MARK[1], MARK
[2], MARK[3], for "B" MARK[2], MARK[2], MARK[2] likes wise.

In a record format it would be displayed as below
A___________________052060080

B___________________060068070

Total length of the record is 20 + (3*3) = 29

This code will process n number of records no matter what
is the size of occur clause but if the length of the
records is beyond 29 then only the job will abend.

I hope this answers your query.
