Chapter 21: Error Messages

This chapter lists the error messages that might be returned while you are developing your Dialog System program.

21.1 Run-time System Error Messages

The following error messages are returned by the Dialog System Run-time System software. If errors are detected while you are running your program through the trap screen, the error message number appears in the error code field and the message is displayed at the bottom of the screen.

There are two types of run-time system error messages: recoverable and fatal. Recoverable errors can be trapped in your program, so you can take corrective action and continue to run the program. Fatal errors cause a message to be sent to the screen then terminate your program immediately. Although you cannot recover from a fatal error during the run of your program, once it has terminated, you might be able to rectify the conditions that caused the error.

Screenset not initialized (fatal)

• You have probably set the Ds-Control field of the control block to a value of "C" before using a value of "N" for a new screenset.

Cannot open screenset (fatal)

• The system has been unable to find a screenset you have attempted to access in your program.

 Error reading file (fatal)

• A disk corruption has occurred.

Invalid screenset (fatal)

• The screenset you are attempting to open is not recognized as a valid screenset.

• You have used an invalid filename.

• If the screenset is from a previous release of Dialog System, ensure it is resaved with the current version number.

 Cannot create panel (fatal)

• There is a maximum of 50 Micro Focus Panels allowed per screen set (Windows only).

 Dynamic internal error (fatal)

• This should never occur. If it does, it might be because a memory limit has been reached. Please contact Product Support.

 Invalid function code (fatal)

• An invalid function was found in the screenset, but Dialog System cannot identify at what stage the error occurred. Check the functions in your screenset. If you cannot find an invalid function, contact Product Support.

 Invalid procedure number (recoverable)

• You have specified a procedure that does not exist. Check that the procedure number you have specified is one that you have already defined.

 Validation program error (fatal)

• The validation program has detected one of errors 010 – 016.

 Invalid data block version number (fatal)

• The Data Block version number in the copyfile does not match the version number in the screenset.

 Panel limit reached (fatal)

• There is a limit of 50 active Micro Focus Panels per screen set (Windows only).

 Error file missing (fatal)

• You have tried to access the error file yourself (see the chapter Programming), but it cannot be found. This error should not occur during normal operation of the Dialog System Run-time System.

 Subscript error (fatal)

• You have used a subscript in dialog that is greater than the size of the associated group.

 Procedure stack overflow (fatal)

• The maximum level of nesting of procedures (that is, XP nesting) is 16.

 Ctrl-break pressed (recoverable)

• Ctrl+Break was pressed while in the Dialog System Run-time software (Windows only). Ctrl+Break detection is only active if the appropriate control parameter is used on the screenset initialization call. Control is passed back to the user program, where you can perform appropriate processing or reinvoke the Dialog System Run-time software.

 Error on trace file (fatal)

• The system has encountered an error, such as a full disk, while trying to access the trace file.

Screenset not found (fatal)

• This error is returned by the common GUI/Character dsrun module for the first screenset load of the run. It indicates that the named screenset has been searched for in both character and GUI form, but has not been located.
