Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

▀ This function assumes that the FCB used as input has been properly
  initialized by a previous call to Int 21H Function 11H (and possible
  subsequent calls to Int 21H Function 12H) and that the filename or ex-
  tension being searched for contained at least one wildcard character.
 
▀ As with Int 21H Function 11H, it is important to use Int 21H Function
  1AH to set the DTA to a buffer of adequate size before using this
  function.
 
▀ Int 21H Functions 4EH and 4FH, which allow full access to the hierarch-
  ical directory structure, should be used in preference to this function.
