This section covers the following topics:
During processing, Natural for DL/I internally checks for DL/I status
codes. Status code checking by the user program is seldom required; only
certain error conditions might require status code checking within a program.
For this purpose, all DL/I status codes have a corresponding Natural error
message. It is possible to check for these errors using an
ON ERROR statement as
described in the Natural Statements documentation.
The error messages generated are in the range from NAT3850 to NAT3899.
This section contains the codes issued by Natural for DL/I in case of abnormal end of execution.
Each abend entry contains suggestions listed in the section Problem Determination Guide on what action is to be taken by the system programmer to solve the problem. In addition, each entry lists the name of the module involved.
The contents of the registers before the abend can be found in the field CAABREGS in the Natural for DL/I common area (DSECT NDCA), at hexadecimal offset +x154. To locate the Natural for DL/I common area, use the register 3 contents or look for the visual identifier "NDCA" in the Natural thread.
