The characteristics specifications for
9-track tape drives with compatibility
feature are:
X' CO'
X'C8'
1600 bytes/inch
800 bytes/inch
~Q1~~ In the course of a system run, a
number of ASSGN statements may be
issued to assign the same physical tape
drive to various symbolic device
addresses. In this case, the tape
characteristics specifications con-
tained in the last ASSGN statement read
for the (physical) drive are valid for
all symbolic device addresses to which
the drive is assigned at that time.
--This operand is used to unassign a sym-
bolic device address.
No!~: An ASSGN statement for SYSRES may be
submitted only to the tape IPL program. An
ASSGN statement for SYSRDR must be sub-
mitted to the card IPL program, and may be
submitted to the tape IPI. and tape Job Con-
trol programs. It must not be submitted to
the card Job Control program.
The CONFG control statement is used to
place the storage-capacity specification
into the communication region of the Basic
Monitor program in main stor~ge. The CONFG
control statement has the following format:

For example, to define a Model 20 with a
main-storage capacity of 8192 bytes, the
CONFG statement is:
1/ CONFG 8
~ct~: rhe communication region of the
Basic Monitor program contains a standard
storage-capacity specification for 8192
bytes. Therefore, the CONFG control state-
ment is reguired only if the storage capa-
city of the user's Model 20 is other than
8K.
The DArE control statement is used to place
the date into the communication region of
the Basic Monitor program in main storage.
