Whether window is opened or closed is written to window open status at PT sta-
tus of PT notify area.
Window screen number and window position (bottom left coordinate) of current-
ly displayed screen is written to window control area.
Checking these areas from the host enables to know the display status of win-
dow. For details, refer to 3-4 Display and Control of Windows (page 298).
Numeral/Character string input field registered on a window is a temporary input
field.
(Only one numeral or character string input field can be registered for a window.)
This input field can be used - in combination with a number of numeral and char-
acter string input fields on base screen - for provisional input before any data is
input into the actual input field on the base screen.
The advantage of a temporary input field is that entries can be input into it while
checking the current setting on the base screen.

However, if there is not even one numeral setting input field (numeric key type) or
character string input field on the base screen, the temporary input field will not
be displayed (cannot be used).
If the temporary input field has fewer digits than the actual input field on the base
screen (integer part + decimal fraction part + decimal point digit + sign digit ), it
will be displayed but can not be used.
If it is not possible to use a temporary input field, the data has to be input directly
onto the base screen.
Focus window is a screen on which currently activated input field (temporary in-
put field) is registered. (In case there are no active input fields on windows even
when multiple windows are displayed, it means that there are no focus win-
dows.)
When the data is input from touch switches or bar code reader, the data is input
to a temporary input field on a focus window.
The focus window is determined by the following rules.
• When only one window has an active temporary input field.
The window with an active input field is a focus window.
• When there are multiple temporary input fields which are active.
The one at the front of all the windows which have active input fields is a focus
window.
