FCBS

Purpose:    Sets the emulation level of FCB system calls, usual for the old
            system versions.

Syntax:     FCBS = <xx[,yy]|ON|OFF>

By default: FCBS = ON

Note:
     The yy parameter has been left for the sake of compatibility with
previous DOS versions. xx values other than 0 correspond to the ON state,
xx=0 - to the OFF state.

     FCBS=OFF saves about 1.5K of system memory. Only the Find First/Find
Next/Create system calls are then available trough FCB. Other calls that
are supported by the standard system interface, are possible only when
FCBS = ON.

     There are programs that employ undocumented FCB fields. In these cases,
as a rule, messages of errors in DOS file system occur. To cure the problem,
the CHKDSK external DOS command or the system- independent programs as
Symantec's Norton Disk Doctor, should be used.
