This method is used with a variable of the FORM data type to retrieve the height of the form in rows. It takes no parameters and returns the information about the form associated with the variable:
variable.GetHeight()
To be able to use this method, you need to use the same variable with the ui.Form.Open() or ui.Window.GetForm() methods first. It returns an integer specifying the number of rows in the form SCREEN section:
CALL form_v.GetHeight()
This method is a legacy one and can be used only in Informix4GL compatibility mode:
