It does not matter whether job type is interactive or batch. What matters
is whether job uses display I/O.
All interactive jobs use it by definition, but if batch job acquires a
display and tries to do display I/O, it will immediately become an
"interactive" in a sense, with all the consequences.

On a server system, does a batch job that runs a pgm that writes to a dspf
run a full server speed, or does it run in the interactive penalty box and
cause the cpu wasting CFINT job to run?
To illustrate my question ...
The code at the end of the email will create a cmd, dspf and cl pgm. The
pgm, cmd and dspf are all named BatMenu.
The cl pgm will prompt a menu on the display and execute the selected
option.
The cmd is used to call the cl pgm with its one parameter: This parm
contains the name of the display device to write the menu to.
The cl pgm is intended to run in a batch job. So it will OvrDspf its dspf
to the device name passed in parm 1.
OvrDspf BatMenu Dev(&Device)
To run the pgm, do the following:
1. Get the device name of a display that has a signon screen ( not
signed on )
2. SBMJOB CMD(BATMENU DEVICE(sssss)) JOB(BATMENU)
When I run this on my system, the job type of the job is BATCH.
My question is: On a server model, does this BATCH job that writes to a
display terminal run at full server speed or does it run in the interactive
penalty box and cause the cpu wasting CFINT job to run?
The code follows. I have included it in case what I am asking is not clear.
Or it might be usefull as tutorial on the use of the Device parm of the
OvrDspf cmd.
Thanks for the help,
Steve Richter
1. Add the following to a srcmbr BatMenu in qgpl/qcmdsrc:
CMD PROMPT('Batch job display test')
PARM KWD(DEVICE) TYPE(*CHAR) LEN(10) +
PROMPT('Device name')
2. Create the command:
CrtCmd qgpl/batmenu qgpl/qcmdsrc batmenu
3. Add the following source code to dspf srcmbr BatMenu in qgpl/qddssrc:
A R BATMENU1
A 2 2'MENU'
A 4 2' 1. SNDMSG'
A 10 2'90. SIGNOFF'
A 12 2'OPTION:'
A OPTN 2 0B 12 10EDTCDE(Z)
4. Create the dspf:
CrtDspf qgpl/batmenu qgpl/qddssrc batmenu
5. Add the following source code to clp srcmbr BatMenu in qgpl/qclsrc:
PGM PARM(&DEVICE)
DCL VAR(&DEVICE) TYPE(*CHAR) LEN(10)
DCLF FILE(BATMENU)
DCL VAR(&JOB) TYPE(*CHAR) LEN(10)
DCL VAR(&USER) TYPE(*CHAR) LEN(10)
DCL VAR(&JOBTYPE) TYPE(*CHAR) LEN(1)
OVRDSPF FILE(BATMENU) DEV(&DEVICE)
/* OVERRIDE YOUR APPLICATIONS DISPLAY FILES HERE. */
B1: DO
CHGVAR VAR(&OPTN) VALUE(0)
SNDRCVF RCDFMT(BATMENU1)
IF COND(&OPTN *EQ 90) THEN(GOTO CMDLBL(E1))
IF COND(&OPTN *EQ 1) THEN(DO)
RTVJOBA JOB(&JOB) USER(&USER) TYPE(&JOBTYPE)
SNDMSG MSG('Job' *BCAT &JOB *BCAT 'is job type' +
*BCAT &JOBTYPE) TOUSR(&USER)
ENDDO
GOTO CMDLBL(B1)
E1: ENDDO
ENDPGM
6. Create the cl pgm
CrtClPgm qgpl/batmenu qgpl/qclsrc
