Hi Savitha,

Syntax Diagram

SET EXTENDED CHECK

Syntax

SET EXTENDED CHECK {ON|OFF}.

Effect:

This statement uses the addition OFF to deactivate the extended programcheck for the following statements, and uses the addition ON to reactivate it. A deactivated extended program check can be reactivated within the same program. The extended program reports a statement SET EXTENDED CHECK OFF without the statement SET EXTENDED CHECK ON and the superfluous statements SET EXTENDED CHECK ON. By default, the extended program check is switched on.

Notes:

This statement can only be used for warnings and errors that the program author can explictly exclude as such.

For individual statements, the extended program check can also be deactivated using pseudo comments.

In this case, deactivation of the extended program check can be overridden by selecting Also display hidden messages (pseudo comments)

Example

The statement SELECT SINGLE reads a single line from the database table TDOKUIMGR. Although this table has several key fields, the entry in the NODE_ID column of the WHERE condition is unique. The warning in the extended program check that the specified key may not be unique is therefore deactivated.

...

SET EXTENDED CHECK OFF.

SELECT SINGLE ref_object

FROM tdokuimgr

INTO docu_object

WHERE node_id = node_key.

SET EXTENDED CHECK ON.

...
