Carriage control byte
Fixed length and variable length print records are described as
follows:
Fixed length print records The carriage control byte for fixed length records is the first byte of
each fixed length record.
Variable length print records The carriage control byte in variable length records immediately
follows the record length for each record.
In both fixed and variable length records, the carriage control byte is
considered part of the data of the record and not part of any other
control bytes associated with the record.
COBOL print tapes
COBOL language programs executed under the US70 operating
system may produce print tapes with up to four different formats.
These formats are a result of changes in device assignments at run
time. Also, reports written by the Report Writer feature of COBOL
may be written to magnetic tape.
Subsequent paragraphs discuss possible formats that may be
processed on the printed system and how they are produced. Use
the following code to interpret the examples:
Note: If the records are variable length, the block and record
counts precede the first character in the examples shown below.
Format 1
This is a printer-destined file assigned to the external name SYSnn
or a report written by Report Writer to the external name SYSnn.
Records of these types of files have a single byte carriage control
character appended to the front of the record.
cc A single byte code for controlling carriage spacing on the
printer.
P COBOL Monitor output code of one byte appended to the
record; indicates the record is to be printed.
c COBOL Monitor output code of one byte appended to the
record; indicates the record is to be punched onto a card.
RC The report code specified in Special Names for the WITH
CODE option on the Report Writer.
