$ErrSet
Increment or clear number of counting errors, set $Errmsg
Note: Most Sirius $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.
The first argument is 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.
Syntax
[%count =] $ErrSet(<span class="term"string)
%COUNT is the number of "counting" errors.
For example
%count = $ErrSet('NASTY ERROR') %junk = $Errmsg
would set %junk to NASTY ERROR and would increment the number of counting errors.
You can also change the number of counting errors (the Sirius ERCNT parameter) with $Resetn.
