drl consop vfd 18/msg,12/word,6/consno tra error (return) tra qfull (return) ... (normal return)
DRL CONSOP allows privileged subsystems to type console commands while executing.
The "error" return is taken if a console command is invalid or the "msg" buffer is at an invalid address. The "qfull" return is taken when GPOP's message queue is full. In this case, you should relinquish and try again.
Note that this is a privileged derail and will cause an abort of the subsystem by TSS if executed without the proper bit set in the user's accounting record.
For compatibility with previous versions of DRL CONSOP, a default value of 3 will be assumed if "words" is zero.
