the procedure waits for the time interval supplied (in seconds) before
processing resumes.
Considerations
CNMREAD processing always sets the &SYS.RETCODE system variable. If
variables are created, the &SYS.VARCNT system variable is set to reflect the
number of variables created.
If you use TYPE=SEG or TYPE=BOTH, you must specify the ARGS or VARS
operand.
NCL sets the &SYS.LOOPCTL system variable to 1000 each time the CNMREAD
verb is executed, unless the user explicitly sets it to 0 (zero).
CNM only receives solicited data. Unsolicited data is read by EMSREAD and
processed by EMSPROC.
See the related verbs CNMALERT, CNMCLEAR, CNMSEND, CNMVECTR, and
EMSREAD in this section.
Examples
