Hi Sararaju,

Quote:

Group of paragraphs is called as section. COBOL has pre-defined sections and user defined sections.

For example INPUT-OUTPUT SECTION, WORKING-STORAGE SECTION are pre-defined. You can define your own section within Procedure division. (for example, SORT / MERGE I/O procedure sections)

Adding to RUPESH...Paragraph needs an EXIT but No section does.

Quote:
4)811 error code define?

More than one row was returned by an embeded query.
May be it is a subquery returning more than one row.

Ensure proper cond specification for the stmt & the data.

Regards,

Priyesh.

Sorry guys for being wrong -818 timestamp mismatch.I wont repeat this again.


As Priyesh Said -811 SELECT statement has resulted in a result table containing more than one row.

Elonics.
