SHOWJCW



SHOWJCW

     Displays current state of one or more Job Control Words
     (JCWs) variables.  (CM)

SYNTAX

     SHOWJCW [jcwname]


PARAMETERS

jcwname             The name of a valid Job Control Word (JCW) variable.
Default is that all user and system-defined JCWs are
displayed.

OPERATION

     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.

EXAMPLE(S)

     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
