ERB458I

Explanation
A START RMF™ or
a MODIFY RMF command was issued
with the data buffer option and a syntax error was recognized in the
data buffer option. The second line of the message repeats the incorrect
input, and an arrow in the third line points to the substring that
could not be interpreted.

System action
RMF rejects
the data buffer option of the START command or the entire MODIFY command.
If the incorrect data buffer option was issued on the START command
together with Monitor I data gatherer options, it is also passed to
Monitor I option processing, which causes this option to be skipped
(as an invalid Monitor I data gatherer option). The data buffer processing
continues without any change of its parameters.

Operator response
Reissue the command with the correct syntax.
See the z/OS RMF User's Guide for
the correct syntax.
