ᑍ Error Code parameter include. As this sample program
ᑍ uses COPY to include the error code structure, only the first
ᑍ 16 bytes of the error code structure are available. If the
ᑍ application program needs to access the variable length
ᑍ exception data for the error, the developer should physically
ᑍ copy the QSYSINC include and modify the copied include to
ᑍ define additional storage for the exception data.

ᑍ Remove an exit program from the exit point and then deregister
ᑍ the exit point. It is not necessary to remove exit programs
ᑍ from an exit point before deregistering the exit point. It is
ᑍ done here only for illustrative purposes.
ᑍ
ᑍ Initialize the error code parameter. To signal exceptions to
ᑍ this program by the API, you need to set the bytes provided
ᑍ field of the error code to zero. Because this program has
ᑍ exceptions sent back through the error code parameter, it sets
ᑍ the bytes provided field to the number of bytes it gives the
ᑍ API for the parameter.
