error = %ERNUM
Return value
error
The code number of the error that was most recently trapped. (n)
Discussion
%ERNUM is the same as %ERROR without any of the optional arguments.
|
All I/O statements and many subroutines update the value returned by %ERNUM. After you get an error with ONERROR or an I/O error list, we recommend that you use %ERNUM to capture the error immediately, before it is updated by subsequent statements and subroutines, and then store it in a local variable for later processing. |
Examples
