Planning Jobs
Figure 2-1 shows the relationship among infiles and FD files in a job
stream. Figure 2-2 shows the order in which the card images from the
files in Figure 2-1 are transmitted to the host.
Figure 2-2 Order of Card Images Transmitted
Host System Job Control
SNA NRJE checks for valid JOB cards, SIGNOFF cards, and host
console commands before transmission. If NRJE detects a SIGNOFF
card, it prints a warning message. The card is not transmitted to the
host.
SNA NRJE requires at least one JOB card whenever a SUBMIT
command is issued. If the
TRANSPARENT parameter is omitted from an
FD card image, SNA NRJE recognizes all JOB cards contained in the
referenced file as job delimiters, not data.
Valid JOB cards are used to break an input job stream into separate
spool files, which are placed in the reader transmission queue. If any
host command card images are between host jobs in an input job
stream, they are sent with the first of the jobs. For example, host
system PRIORITY cards have no effect on the host when associated
with the second or subsequent job in a job stream. Figure 2-3 shows two
jobs that are submitted to SNA NRJE together. SNA NRJE merges
Infile A with FD file RED. The first priority card has the desired effect
