:SHOWQ
The :SHOWQ command is a much older MPE command - existing long before MPE/iX. The
output of :SHOWQ is also much more "column oriented" (compared to :SHOWPROC). In
general, users are discouraged from making assumptions regarding specific column
numbers in command output. Various CI functions have been added in MPE/iX to assist
users in parsing output without relying on column (e.g. the "word" function). However,
given the fact that :SHOWQ has been around for a very long time, its columnar output,
and given older scripts (etc.) tend to make more assumptions about column, we opted not
to change the columns for :SHOWQ output. As a result, 5-digit PIN numbers will "run
together" with the field that follows the PIN in :SHOWQ output. Fortunately, the field
following PIN in :SHOWQ is a Job/Session number. Job/Session numbers are displayed as
#Jxxxxx or #Sxxxxx. As a result, the output from :SHOWQ is still fairly "readable" even if
a 5-digit PIN runs together with a Job/Session number.
