where:
LD
represents a 2-charater
mnemonic. Any mnemonic other
than RD and XX can be used
~
Th is mnemonic may indicate a
device type the logical device
is to represent; e.g., LP for
Line Printer, as required by the
printer symbiont.
yy
is a pseudo-device
'number and

Description
The fi rst device file entry, OF N
=
1, must be
one of the following:
7012/dn,F
8091/dn,F
4191/dn, F
I
7193/dn,F
Model 530 on Iy
This parameter is used to reserve entries for
RAO/disk file OFNs, either for background
or foreground use.
B specifies background,
F, foreground.
SYSGEN always allocates two to six fore-
ground RAD/disk DFNs for use by th~ Monitor
in addition to the number of RAD/disk fore-
ground OFNs specified by the user.
Hence,
the total size of the File Control Table will be
the sum of the number of nondisk DFNs as-
signed, plus the total number of OF Ns reserved
for foreground use plus two (to six), plus the
number of DF Ns reserved for background use
plus nine, plus one if 01 is specified and one
if
00
is specified (see example).
Logical Device (lD) definition is used to
reserve entries for lD OFN groups, either
for background or foreground use. B specifies
background, F foreground.
The pseudo-device number, yy, is a channel
number that typically is unused by any real
device. A unique channel number should be
used for each LO DF N group.
