Description
The Method called on error command returns the name of the method installed by the ON ERR CALL command for the current process.
If no such method has been installed, an empty string ("") is returned.
Example
This command is particularly useful in the context of components because it enables you to temporarily change and then restore the error-catching methods:
$methCurrent:=Method called on error
ON ERR CALL("NewMethod")
` If the document cannot be opened, an error is generated
$ref:=Open document("MyDocument")
` Reinstallation of previous method
ON ERR CALL($methCurrent)
