Set or return the value of a screenfield (ScreenField class)


This property sets or returns the value of a ScreenField. The value is set from or copied to a User Language string, and it may be from 0-255 characters in length.

Syntax

%currentString = sfield:Value sfield:Value = newString

Syntax terms

%sfield
A reference to an instance of a ScreenField object.
newvalue
The string value to assign to %sfield.
%string
A User Language string variable to contain the returned %sfield data.

Usage notes

After a Read method (“Read function” on page 904) on the Screen object, you use the Value method to get any user-entered data for a non-protected field.

For an example using Value to set field display data, see “Screen class example”. For an example using Value to get user-entered data, see the example below.

See also the AddField method, whose Value parameter can set display data when the ScreenField is instantiated.
