Its not like that the memory will be problem , if iam using OCCURS 0.

Only initially it will allocate 8K bytes

When it will cross 8K,then it will allocate another 8K bytes like page in OS concept.

HI,

System itself assigns more memory automatically when it exceeds the limit with OCCURS 0 usage.

The objective of setting the value of an occurs for an internal table is a question of optimization. The following facts should be taken into account when making such decision.

1) The complete data area of a program is 64000 bytes.

2) The initial size declared is kept in roll area (quicker access to program)

3) Data entered that exceeds the initial size stores in the roll file (Slower access to program)

You should also analyze the expected volume and access rates before making the decision.

Hope this helps.

Using the OCCURS statement allocates memory for the interna table. When saying OCCURS 0, you are simply not allocating any memory, rather the system will increment the memory allocation as it is needed for the internal table.
