NCL Exits › Standardized Structure

Standardized Structure

For ease of maintenance and debugging, an NCL exit should have the following structure (as discussed in this appendix):

• A commented introductory section
• A procedure that validates and interprets the parameters passed to the exit and converts them to variables
• The core processing code that performs the main function or functions of the exit
• A final piece of code that sets a return code and passes control back to the caller

A sample NCL exit procedure, $RMPB06S, is supplied with Automation Services for your reference. This procedure creates a SOLVE:Problem record.
