CONTASK CONTASK contains data and control information pertinent to the control and communication between virtual and real terminal console tasks and command streams. The RDEVCON field of the RDEVBLOK and the NICQPNT field of the NICELOK point to CONTASK. 0 CONPNT CONRE'lN 8 C*1 I C*2 10 18 20 28 30 Hexadecimal Field Displacement Name o 4 8 9 A C 10 10 14 15 16 10 18 20 28 30 CONPNT DS CONRETN DS CONSTAT DS liit§ CONOUTPT EQU CONRESP EQO CONACTV EQO CONCNTL EQO CONESCP EQO CONRTRY BQU CONSPLT EQO CON SYNC EQO CONPARM DS CONTSKSZ DS CONOSER DS CONCCi1 DS ORG CONADDR DS CONFLAG DS CONDiC DS CONCNT DS ORG CONCOMND DS CONCCi2 DS CONCCi3 DS CONCCW4 DS CONDATA DS CONTSIZE EQU I CONTSKSZ CONUSER CONCCW1 CONCCW2 CONCCW3 CONCCW4 CONDATA (Variable Length) 1F 1F 1X in CONSTAT -X'80'-- X'40' X'20' X'10' X'08' X'02' X'01' 11 1H 1F 1D CONCCi1 1F 1X 1X 1H CONADDR 1X 1D 1D 1D OC Field Description, Contents, Meaning Pointer to next CONTASK Pointer to SAVEAREA for return C*1 CONTASK status control flags Generate CONTASK output Respcnse expected from this CCNTASK CONTASK is active on real device This is a centrol CONTASK cnly CONTASK contains device deFendent data Retry operation in progress Output data being split via RDEVLLEN CONTASK for synchronization enly C*2 DMKQCN parameter flags (see "APFendix A.
