Reading the Disk with the CATalog? Query
This example program uses the CATALOG? query without the ALL option
to read the catalog of the currently selected disk drive. However, if you do
not use the ALL option, the query only returns a 51-character field. Keep in
mind if you use this program with a DOS disk, each filename entry will be
truncated at 51 characters.
