A user-assigned numeric identifier for the form field.
Valid Values
An integer (0 to 999)
If no number is assigned, 0 is used.
Remarks
FNum can be used in an application program to identify the form field that had focus when control returned to the program. (See $FieldNum, $MenuItemNum, and $MouseFieldNum in the Language Reference.) For form fields with no transmit attributes, FNum is usually left at 0 unless the BY FIELDNUMBER option is to be used to set the tab order (see the WINDOW SET TABORDER command in the Language Reference).
