[AccessD] Alias Question

[Stuart McLachlan]

Two possibilities:
1. If you want to abbreviate a long name, or 
2. If the original name of a function contains characters that are illegal in a 
function name in your development enviornment
e.g.:
DECLARE FUNCTION LegalName ALIAS "Illegal$Name" ...
DECLARE FUNCTION LegalName ALIAS "3IllegalName" ...
DECLARE FUNCTION LegalName ALIAS "_IllegalName" ...
