%STATUS{(file_name)}%STATUS returns the most recent value set for the program or file status. %STATUS is set whenever the program status or any file status changes, usually when an error occurs.
If %STATUS is used without the optional file_name parameter, then it returns the program or file status most recently changed. If a file is specified, the value contained in the INFDS *STATUS field for the specified file is returned. The INFDS does not have to be specified for the file.
%STATUS starts with a return value of 00000 and is reset to 00000 before any operation with an 'E' extender specified begins.
%STATUS is best checked immediately after an operation with the 'E' extender or an error indicator specified, or at the beginning of an INFSR or the *PSSR subroutine.
For more information, see File Operations, Result Operations, or Built-in Functions.
The operations that set %STATUS are:
*..1....+....2....+....3....+....4....+....5....+....6....+....7...+....
* The 'E' extender indicates that if an error occurs, the error
* is to be handled as though an error indicator were coded.
* The success of the operation can then be checked using the
* %ERROR built-in function. The status associated with the error
* can be checked using the %STATUS built-in function.
