Increment or clear number of counting errors, set $Errmsg
Note: Many $functions have been deprecated in favor of Object Oriented methods. There is no OO equivalent for the $ErrSet function.
This function allows you to set or clear the current error message (which is returned by $Errmsg) and to increment or clear the number of "counting" errors.
The $ErrSet function accepts one argument and returns a number indicating the current number of counting errors. It is a callable $function.
Syntax
[%count =] $ErrSet(string)
Where:
| %count | The number of "counting" errors. |
|---|---|
| string | A string indicating the message to be returned by the next $Errmsg call. If this argument is omitted or null, the current error message is cleared and the number of counting errors is set to 0; otherwise the number of counting errors is incremented. |
Example
The following statement sequence sets %junk to NASTY ERROR and increments the number of counting errors.
%count = $ErrSet('NASTY ERROR') %junk = $Errmsg
Note: You can also change the number of counting errors (the ERCNT parameter) with $Resetn.
