Version: 2.00
Declarations nescessary for an application program using the file
system.
JKK 840524 transferf partioned into getf and putf
JKK 840604 declarations prefixed by fs_
JKK 840711 fs_pagebuffer_type added
JKK 840726 fs_lookup, fs_set_tail added
JKK 840921 directory changed to catalog
BB 860807 typesize introduced
BB 860916 tail in file_info_type moved
BB 860923 fs_catalog_connection has now dynamic pool
BB 860924 the new predefined type double used
BB 870825 Name changed from fsenvir to fs3502env
