Command List XII
Commands STREAM thru XEQ
use for this input. As a result, the listing device that corresponds to the streaming device
(not necessarily your terminal) displays the job number assigned by MPE/iX and the
listing generated by the job.
When you enter STREAM without an input file (that is, with the terminal as the default
input device) during a session or a job, MPE/iX prompts you for input by displaying a
greater than (>) character. When you enter STREAM for a device other than your terminal,
MPE/iX does not print the prompt character.
How to Stream Jobs
Begin each job in the input file with the !JOB command and terminate it with the !EOJ
command. Begin all commands with an appropriate substitute (other than colon)
character, as in !JOB. When the input file is spooled to a disk, MPE/iX replaces the
substitute command identifier with a colon, so that the data files are properly interpreted
when executed.
After reading the !EOJ command that terminates the job, MPE/iX assigns each job a
unique job number (JobID). MPE/iX also assigns each job a preset priority, unless you
specify otherwise in the JOB command, and processes the job independently of the
initiating job or session. Regardless of which device you use to submit the input file, all
jobs in that file are treated as though they originated on the unique streaming device
designated by the system operator (with the STREAMS command). The listing for each
spooled job and the job number are written to the standard list device that corresponds to
the streaming device. You may, however, use the OUTCLASS= parameter of the JOB
command to direct the listing to another device.
How To Time Schedule Jobs
You may specify the time a job is to enter the WAIT state in absolute or relative time.
Absolute The user supplies an exact time for the job using the AT parameter with or
without the DAY or DATE parameter.
Relative The user specifies a time offset from the current time using the IN
parameter.
If the time specified is the same as the current time, the specified job logs on immediately.
If the time specified is earlier than the current time, and DAY and DATE are not specified, a
warning message is generated, and the job is scheduled for the specified time tomorrow.
Otherwise, any time in the current century can be specified.
If no errors are detected, a JobID is displayed on the user's screen. If more than one job is
included in the inputfile, each job is assigned a unique JobID, and all of the jobs are
scheduled at the same time.
When a job is scheduled for a future time, it enters the SCHED state. When the specified
time is reached, the job enters the WAIT state and is executed when system variables
allow.
Terminating Streamed Jobs
To terminate interactive job input, enter a colon (:). In response, MPE XL ceases
prompting for batch job input and instead prompts you for another MPE/iX command:
>: ** Denotes end of batch job input **
