SHOWJCW
Displays the current state of one or more job control word (JCW)
variables.
Syntax
SHOWJCW [jcwname]
Parameters
jcwname The name of a valid job control word (JCW)
variable. Default is that all user-defined and
system-defined JCWs are displayed.
Operation Notes
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 classed as
variables of type JCW. Specifying a particular JCW (user-defined,
system-defined, or system-reserved) displays the value 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 USER.TECHPUBS;COMPILE FAILED
!ELSE
! TELL USER.TECHPUBS;COMPILE COMPLETED
!ENDIF
Use
This command may be issued from a session, job, program, or in BREAK.
Pressing Break aborts the execution of this command.
Examples
To show the current state of all user-defined 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
