TMask = class
class PASCALIMPLEMENTATION TMask : public System::TObject
TMask allows the comparison of strings containing wildcards to a file mask.
Use TMask to determine if a string matches the format described by a mask. The mask contains literal characters, wildcards that can match any character, and sets that match a single character that is included in the set.
Note: Do not confuse TMask with the EditMask of a field or masked edit object. While both are used for comparing strings to a symbolic description of valid values, the special mask symbols and matching rules are completely different.
