In the UK we have Postcodes eg DN45-4LW.

Each area is split up into post towns say Leeds = LS
the Street will be 56 which makes a postcode of LS 56

If a user types LS 56 how can I just check for the first characters Say  LS = True and mask the 56.

Well, you could use a TMaskEdit to control how they enter it, or write an event handler for OnKeyPress for the edit control and when they have typed in the first two chars do what you need to do or simply disregard the key press by setting key to #0.

Or, if you just want to peel off the first two chars from what they typed in do:

MyString = copy(EnteredString, 1, 2);
if MyString = 'LS' then ...


Cheers,

Raymond.
