Every Destination Screen has an invoke script which controls how it is displayed. Here is an example of a script that invokes a SHOWORDER screen when an order is selected in the instance list:
First the script navigates to the 5250 junction screen GETORDER which is used to select which order is to be shown:
...
NAVIGATE_TO_JUNCTION("GETORDER");...
...
It
...
then
...
makes
...
sure
...
that
...
we
...
get
...
to
...
the
...
GETORDER
...
screen.
...
If
...
this
...
check
...
fails
...
an
...
error
...
message
...
is
...
shown:
...
if ( !(CHECK_CURRENT_FORM("GETORDER", "Unable to navigate to form GETORDER")) ) return;
...
...
Next
...
the
...
script
...
retrieves
...
the
...
current
...
order
...
number
...
from
...
the
...
instance
...
list
...
to
...
the
...
GETORDER
...
screen.
...
Typically
...
you
...
need
...
to
...
edit
...
this
...
part
...
of
...
the
...
script
...
(see
...
Replacing Hardcoded Employee Number with Current Instance List Entry):
SETVALUE("ORDERNUMBER", objListManager.AKey1\[0\] );
...
...
And
...
then
...
presses
...
the
...
Enter
...
key
...
to
...
process
...
the
...
GETORDER
...
screen:
...
SENDKEY(KeyEnter);
...
...
Finally
...
the
...
script
...
makes
...
sure
...
that
...
screen
...
SHOWORDER
...
has
...
arrived
...
back
...
from
...
the
...
IBM
...
i
...
and
...
is
...
ready
...
to
...
be
...
displayed.
...
If
...
this
...
check
...
fails,
...
an
...
error
...
message
...
is
...
shown:
...
if ( !(CHECK_CURRENT_FORM("SHOWORDER", "Unable to display order number " + objListManager.AKey1\[0\] )) ) return;
...
...
...
