>>To store information that is then available to all methods, objects, code etc. in your form. For example, you might have a property frmIndex which stores the active index of the table showing in a grid. If the user wants to change how the data is ordered (from last name to zip code for example) you store the change to the form property.

Not exactly. Use properties like variables. For instance if you have a property to store the index tag name, (as above), then you would store the active tag in the property.

** User chooses to order by Last Name
if thisform.cIndex <> 'LAST'
sele NAMES
set order to tag Last
thisform.cIndex = 'LAST'
endif

Note that the code is skipped if the value didn't need changing.
