Type III C lass A Program

WRTAPE
Purpose:
WRTAPE copies fixed-length format files from disk to tape·.
If the filetype is LISTING, assembler and compiler
carriage-control codes are translated to machine cod.es.
Format:
IWRTAPEI fname ftype
fname ftype specifies the file to be copied.
Usage:
WRTAPE copies files from any disk to TAP1. Records are
blocked in groups of ten" and the record format must be of
fixed length less than 256 bytes. No end of file is written
on the tape, and the tape is not rewound when the command
completes.
Although WRTAPE handles any file of the format described
above. it is specially designed for LISTING files created by
the ASSEMBLE and FORTRAN commands. These files contain a
carriage control code for the offline printer as the first
byte of each record. WRTAPE translates the code into a
machine code for the printer. Files are written on the tape
in the same format as if the ASSEMBLE command had been
specified with the (LTAPn) option. This format is
acceptable to the TAPRINT command.
Notes:
a. WRTAPE does not write an end of file on the tape on
completion, nor does it position the tape past any existing
files. Use the facilities of the TAPE command for
positioning. To mark an end of file for TAPRINT, write two
end-of-file marks .•
h. Under CP. the tape must be attached by the operator.
WRTAPE expects TAP1,. addressed at 180, which should be
specified when you request the operator to attach the tape.
c. Tape files written with WRTAPE are not suitable for
rereading with TAPE LOAD.
Responses:
None.
