The &CNMCLEAR verb clears all outstanding CNM reply data solicited by this NCL user.
This verb has the following format:
&CNMCLEAR
The &CNMCLEAR verb is used within a procedure to clear all outstanding CNM reply data previously solicited using an &CNMSEND request. This verb would typically be invoked when a procedure in which &CNMSEND has been used is about to terminate and some possibility exists that not all solicited data has been processed. It is also useful in purging any such unprocessed data in order that the results of a subsequent &CNMSEND is guaranteed to be the next available for processing with an &CNMREAD statement.
&CNMCLEAR can be issued at any time to clear the CNM reply environment, regardless of the status of &CNMSEND/&CNMREAD processing.
No useful purpose is served by issuing an &CNMCLEAR from CNMPROC.
