As these examples demonstrate, it is a bit hard to read and to find in the ICKDSF line output.
Probably some REXX-based procedure might have to scan through the ICKDSF SYSPRINT
output, which is directed to a data set. ICKDSF asks for a JCL DD statement for each single
volume to query when the volume is ONLINE to the system. This is not very handy. So, we
are back to the TSO CQUERY command which does not need any additional JCL statements
and does not care whether the volume is ONLINE or OFFLINE to the system. TSO provides a
nicely formatted output as the following examples display, which still might be directed to an
output data set, so some REXX procedure catches the concerned numbers.
