COLLECT KEYWORD

COLLECT: -

      Collect keyword first, checks the internal table whether the record is available or not based on the key field. If not it acts like append (record adds last). Other wise it adds the numeric fields from work area to number field in the internal table.

Syntax: - Collect <wa> into <it>

NOTE: Whenever we are working with collect keyword then we must declare other than numeric (data types) files are unique.
