Options for modifying Variables info:

After double-clicking a variable name 
on the main window - a dialog window is
displayed.

The Variable name and its length will be
displayed.

If this Variable is a KEY field - choose
one of the available indexes from the 
ComboBox.  (But first, set the 'Unique
Key' Checkbox to the correct setting).

Typing in a new Field name and length,
you can:

Select 'Insert' to insert it after the
field selected.

Select 'Update' to replace the existing 
values.

The 'Delete' option will remove the 
selected field (without checking if
the values have changed).

The 'Close' will close the dialog
without making further changes.

Don't be alarmed by the odd characters
next to the length value in the main 
window.  This is the KEY information.

Format is:

VariableName  Length-Unique-Key-Index#

where:
VariableName:  The name you typed in.
Length:  The length of the Variable
Unique:  'U' = unique key
         'n' = non-Unique
Key:     'k' denotes a KEY Field
Index#   a value of 1-9

This is for information only.  You do 
NOT need to enter this format.  That is
done via the Field Update Dialog window.
