10 Arguments:
11 signal_names
12    are the names of one or more IPS signals to be masked.  The signal
13    names must be defined in sys_info$ips_mask_data.  Presently the
14    defined signal names are quit, alrm, neti, cput, trm_, sus_, wkp_,
15    pgt_, system_shutdown_scheduled_, and dm_shutdown_scheduled_.
16    Supply either signal_names or -all.

19 Control arguments:
20 -all, -a
21    sets the IPS mask to unmask all IPS signals.
22 -brief, -bf
23    suppresses printing of the previous state of the IPS mask after
24    setting it.
25 -long, -lg
26    prints the previous state of the IPS mask after setting it.

30 Notes: If all undefined IPS signals are either masked or unmasked and
31 you give -long, they are not mentioned; if, however, some are masked
32 and others are not, an octal list is printed.  This can only happen
33 when you specify an invalid (probably uninitialized) value in a call to
34 set that mask.
