; *** Edit 33 to PTYCON.MAC by GSCOTT on 13-Aug-87, for SPR #21652
; After installing edit 32, PTYCON doesn't go back into terminal input wait
; properly if a command is being typed in at the same time that output from a
; subjob is being displayed. This edit also makes PTYCON check for subjob
; output to be displayed after each "subjob-text" command.
; *** Edit 32 to PTYCON.MAC by GSCOTT on 14-Apr-87, for SPR #21346
; Fix PTYCON not to generate extra PTYOPC interrupts, not to enable PTYOPC when
; connected to a subjob, and to reenter a WAIT JSYS instead of going back to
; COMND when PTYOPC interrupts us causing a PTY Hungry interrupt.
; *** Edit 31 to PTYCON.MAC by LOMARTIRE on 31-Mar-86, for SPR #20838
