fileType$ = FILES$
Returns the file type of the last file returned by the
) function, as a 4-character string. If the user clicked "cancel" in response to the last File Open dialog, or if the
) function has never yet been executed, then the
FILES$ function returns an empty (zero-length) string.
In some cases it's useful to express the file type as a 4-byte long integer rather than as a string. Use the
MKI$ function and the
CVI function to convert between these two forms.
