Field Naming
With the exception of trim fields, which are created without a name, all scalar fields are given a default name at the time they are created. The default names have the form, fieldn, where n is a number.
In general, you should change the default name to something more meaningful so that your 4GL scripts are easier to understand. Some examples of meaningful names are:
exitbtn
A button that says “Exit”
cancelbtn
A button that says “Cancel”
emp_table
A table field that is used to display employee information
