ASSIGN Command
access-spec
is the access mode for logical-unit. It specifies the type of file operations
that can be performed. The possible values for access-spec are the
following:
I-O
INPUT
OUTPUT
I-O
means that processes can both read the file and write to it.
INPUT
means that processes can only write to the file.
OUTPUT
means that processes can only read the file.
CODE file-code
assigns a file code to logical-unit. Specify file-code as an integer in
the range 0 through 65535. The default value is zero (0).
REC record-size
sets the length of records in logical-unit. Specify record-size as an
integer in the range 1 through 65535.
BLOCK block-size
sets the size of the data blocks used by logical-unit. Specify block-
size as an integer in the range 1 through 65535.
Considerations
•
If you enter the ASSIGN command without any variables, SCF displays all the
current assigned values.
•
Use the CLEAR command (described on page 5-40) to delete existing assign
messages.
•
If you specify logical-unit without other parameters, SCF displays the current
assigned value for logical-unit.
•
SCF creates an assign message for each ASSIGN command, up to a limit of 50
assign messages. A new process must request its assign message following
receipt of the startup message. All assign messages are read from TACL, and the
ones set in SCF are passed to the new process.
