IDCMGENP27 - variable-name is not defined to allow a NULL value, a RUN-time error will occur if the sending expression results in a NULL value

Reason:

The evaluation of a function or expression can give a result of NULL. When variable-name is assigned to NULL, a run-time error results. This message is only a warning. No run-time error need result if the program is coded appropriately.

Action:

No action is required. However, you can assure that a run-time error does not occur by rewriting your program appropriately:

• Code the program so that the assignment of variable-name to NULL does not occur at run-time in the statement flagged by this warning.
• Code an error procedure that takes account of the possible run-time error for the statement flagged by this warning.

Consult the Programming Reference Guide for further information.
