Automatic management of errors

ErrorPropagate (Function)

In french: ErreurPropage

Propagates a non-fatal error that can be processed by the calling code if the management of non-fatal errors is enabled for this code (in the code editor or by ErrorChangeParameter).

The error is processed by the higher level if:

an error process was enabled by the higher level.
the error is not managed by IF ... NOT or by the ErrorOccurred variable.

ErrorPropagate([<Message>])

<Message>: Optional character string

Additional message that can be added to the error. This message is inserted at the beginning of the error.

Versions 26 and later

Propagate a non-fatal error by changing the Error( number and adding a message if necessary) Hide the details

ErrorPropagate(<Number> [, <Message>])

<Number>: entier

Error number, defined by the developer. This number must be included between 1 and 1000. This number replaces the existing error number..

<Message>: Optional character string

Additional message that can be added to the error. This message is inserted at the beginning of the error.

Remarks

How to get information about the error processed?

ErrorInfo returns information about the error.

Use example

Purpose: Encapsulating fOpen in a procedure while implementing the error of fOpen (if it occurs):

PROCÉDURE OpenFile(LOCAL sFileName is string)

fOpen(sFileName)
IF ErrorOccurred = True THEN
ErrorPropagate()
RETURN // or RESULT
END
...

Then, you have the ability to call the OpenFile procedure:

...
OpenFile(sFileName)
IF ErrorOccurred = True THEN
// process the error
END

Remark: An equivalent process can be performed with the mode for automatic management of errors.

Special case

The mechanism for processing the error, regardless whether it is managed automatically (window for error management) or by programming (ErrorChangeParameter), is not triggered if the WLanguage function or the user procedure is found in one of the following cases:

IF NOT <Function or procedure> THEN
// process the error
END

<Function or procedure>
IF ErrorOccurred = True THEN
// process the error
END

The mechanism considers that the error is processed by programming and the automatic process is not triggered.
