Displays current state of one or more Job Control Words
(JCWs) variables.
SHOWJCW [jcwname]
jcwname The name of a valid Job Control Word (JCW) variable.
Default is that all user and system-defined JCWs are
displayed.
The SHOWJCW command is used to display the current state of
one or more Job Control Words (JCWs). Job Control Words in
MPE/iX are now classed as system variables of type JCW.
Specifying a particular JCW (user- or system-defined, or
system-reserved) displays the state of that particular JCW.
If you do not specify a particular JCW, user-defined and
system-defined JCWs are displayed. The value of the third
type of JCW, system-reserved JCW, is displayed only if you
specifically enter its jcwname. The SHOWVAR command can be
used to show variable values as well.
You may retrieve the value assigned a JCW with the FINDJCW
and HPCIGETVAR intrinsics.
You may test the value of a JCW with an IF or WHILE
command. In this way, the value of a given JCW can be used
to conditionally execute another instruction or set of
instructions. For example
!CONTINUE
!SPL MYPROG,MYUSL
!IF JCW>=FATAL THEN
! TELL MAC.TECHPUBS;COMPILE FAILED
!ELSE
! TELL MAC.TECHPUBS;COMPILE COMPLETED
!ENDIF
This command may be issued from a session, job, in BREAK, or
from a program. Pressing [Break] aborts the execution of
this command.
To show the current state of all user- and system-defined
JCWs, enter
SHOWJCW
JCW = 0
CIERROR = 0
To display the current state of a valid user-defined Job
Control Word named JCW1, enter
SHOWJCW JCW1
JCW1=3
To display the contents of a system-reserved JCW, enter
SHOWJCW HPDAY
HPDAY=4
