DRL CONSOP (octal -2) - type console commands.

Usage:

drl     consop
vfd     18/msg,12/word,6/consno
tra     error (return)
tra     qfull (return)
...           (normal return)

Where:

msg

is the address where the BCD console command is stored. The first word must be six BCD characters which is the console command, left-justified in a word of blanks. The remaining words can be in any format that is acceptable to the eventual message processor.

words

is the number of words in "msg".

consno

is the console number (0,1,2,3).

Description:

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.

Notes:

For compatibility with previous versions of DRL CONSOP, a default value of 3 will be assumed if "words" is zero.
