Int 21H Function 4EH
   Summary  Notes  Example  Back
──────────────────────────────────────────────────────────────────────────────
 
▀ This function assumes that the DTA has been previously set by the program
  with Int 21H Function 1AH to point to a buffer of adequate size.
 
▀ The * and ? wildcard characters are allowed in the filename. If wildcard
  characters are present, this function returns only the first matching
  filename.
 
▀ If the attribute is 00H, only ordinary files are found. If the volume
  label attribute bit is set, only volume labels will be returned (if any
  are present). Any other attribute or combination of attributes (hidden,
  system, and directory) results in those files and all normal files being
  matched.
