Like the FGETINFO intrinsic, the FGETKEYINFO intrinsic
provides access and status information about the keys of a KSAM file. It
provides detailed information about the key location, type, and length in a
parameter format similar to the FOPEN intrinsic key parameter. The
FGETKEYINFO intrinsic also provides access information, such as a
count of the number of times the key file has been accessed by various
intrinsics, or the date and time the file was created, closed, updated, or
written to.
