Either an NCP value greater than one was specified in the ENV attribute or a STRNO value greater than one was specified in the AMP parameter in the DD statement. For VSAM files, only one outstanding operation is allowed. An operation with the EVENT option must be processed before another operation is started.
The ERROR condition is raised.
Ensure the NCP or STRNO value for a VSAM file is one if the EVENT option is involved, or modify the program to use operations without the EVENT option to allow concurrent operations on the data set.
