Copying tapes on the 1906A

1. PROGRAM FR80 COPY

This program will copy a complete FR80 LOADGO Display tape (either 7-track/556bpi or 9-track/1600bpi). The tapes may be either standard or non-standard, but care must be taken over tape ownership. Note that NUTS will only accurately copy 9-track to 9-track tapes since data conversion is required between 7 and 9-track and even-parity filemarks are used on 7-track.

(a) Input Device and Format

The program may be issued from:

(1) 1906A Operators' Console

Format: FR80 COPY,PARAMETERLIST

(2) MOP console

Format: RJ job name,: GSIN10.FR80COPY,PARAM(parameterlist) ,JD (JT60SECS)

(3) Card Reader

Format: RJ jobname,username, :GSIN10.FR80COPY,PARAM(parameterlist),-
JD (JT60SECS)

(b) Parameters

INxx magtapedescription. This specifies the tape to be read. 
OUTxx magtape description. This specifies the tape to be read. 

In both these parameters, xx should be 7T for 7-track tape and MT for 9-track. The magtapedescription should follow the usual TASK convention (see Appendix 1 for example).

*NM

This gives the user name under which the job is to be run (if issued from 1906A Operators' console - default is :GSIN11 directory :FR80TAPES).

DY directoryname 

This gives the name of a directory which is to be selected before execution.

Examples of the use of these parameters are given in Appendix 2.

3. Tape Ownership

Non-standard and Xenotapes can be copies without difficulty. Worktapes must be DEADed and then accessed by tape serial number as insecure tapes. These tapes are to be returned to the Magnetic Tape Librarian for evaluation and subsequent NEWing back into the system. Owned tap e s must either be trapped to the issuer of the job, or run under his username (hence *NM parameter). Tapes which are in a subdirectory will have to be accessed using DY to select the required directory. The owner of the tape should be consulted before any copying is attempted.

Magnetic Tape Description

9-track tape               (1234)
7-track POOLTAPE           (?,COPY7000123(PRTRACK7))
9-track POOLTAPE           (?,COPY1234)
7-track Non-standard       (IBM123(NONS,PRTRACK7))
9-track Non-standard       (IBM917777(NONS,PRTRACK9))
7-track Xenotape           (1234X,tapename(PRTRACK7))
9-track Xenotape           (1234X,tapename(PRTRACK9))

APPENDIX 2

Examples of use of parameters

From 1906A Operators' console:

1. 7-track tape to 7-track POOLTAPE

FR80 COPY,IN7T(7000365),0UT7T(?,COPY7000365(PRTRACK7)),JD(JT60SECS) 

2. 7-track non-standard tape to 9-track POOLTAPE

FR80 COPY, IN7T(TAPE714(NONS)),OUTMT(?,COPY714) 

From MOP console in appropriate-directory:

1. 9-track tape to 9-track POOLTAPE

RJ jobname,:GSIN10.FR80COPY,PARAM(INMT(1234),OUTMT (?~COPY1234)),- 
JD (JT60SECS,MT2) . 

2. 9-track non-standard to 7-track POOLTAPE

RJ jobname,:GSIN10.FR80COPY,PARAM(INMT(TAPE917(NONS)),OUT7T(?,COPY917-
(PKTRACK7))),JD(JT60SECS,MT1) 

From Card Reader:

1. 7-track to 9-track POOLTAPE

RJ jobname,username,:GSIN10.FR80COPY,PARAM(IN7T(7100034),OUTMT- 
(?,COPY7100034)),JD(JT60SECS,MT1)
