Edit button:
Click this button to edit the file (~.vts) for setting the character
strings used to create messages to be displayed.
For an explanation of the editing method, see “Configuring and
editing text files” located in the text character string indication
control.
Assign Link Number:
To indicate the relation with the “History Display button control”,
which is a function to be accomplished in cooperation with a
button control, assign a necessary link number. Numbers from 0
to 30 can be specified throughout the custom screen project. A
number of 0 may be specified if no link number is necessary;
there may be multiple 0s. The history message indication control
having the assign link number that matches the “Link Number at
output button” of a history indication button control will perform
the operation specified for the history indication button, such as
page switching.
Reference Link Number:
If you have created a summary/history screen and a detail screen
separately with two history message indication controls, when a
detail display message display switching operation command is
transferred from the button control linked with the control
currently displaying a summary/detail screen to the control that
displays a detail screen, the history message indication control
that is assigned this “Reference Link Number”, specified for the
control that displays a detail screen, is referenced to decide on
which detail message to display. Specify the “Assign Link
Number” of the control to be referenced so that the detailed
message of that control is displayed. To switch between
summary/history screen and detail screen using a single control,
specify the same number as the “Assign Link Number” of the
control. If you leave the number 0, the system will evaluate this
as the absence of the control to be referenced, and a detail screen
cannot be displayed.
Summary/History Display:
This item is checked if you select “Summary Display”, “History
Display”, or “Detail Display” for the first time display property.
History Block Number:
For history display, select a number from 1 to 4 to specify the
“History Display” whose contents are to be displayed.
You can specify the history block number 0 if the history
message indication control is to be used for a detail screen only.
CAUTION
The history message indication control indicated by
the “Reference Link Number” of such a control for a
detail screen only may be of the summary/history
display type with a history block specification or of
the message display type. Do not, however, mount
a history display switch button for a control for a
detail screen only.
