Paper No 13: Copying FR80 Data Tapes

R E Thomas

6 November 1975

The following program will copy a complete FR80 Load-go Displayer tape (either 7/556 or 9/1600) on to another tape (either 7/556 or 9/1600). The tapes may be either standard or non-standard ICL, but care must be taken over tape ownership (see notes at the end of this paper). 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.

Macro 

:GSIN10.FR80COPY

Parameters 

INxx magtapedescription

This specifies the tape to be read. 

OUTxx magtapedescription

This specifies the tape to be written.

In both these parameters, xx should be 7T for 7-track tape and MT for 9-track. The magtapedescription should follow the usual TASK conventions. 

*NM username

This gives the username under which the job is to be run (if issued by the operators). 

DY directoryname

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

Examples

RJ    myjob,:GSIN10.FR80COPY,PARAM(parameterlist),JD(JT30SECS) 
FR80 COPY,parameterlist

The second version would be issued by the Operators.

Examples of parameters

(a) Copy 7-track tape to 9-track 

IN7T (7000304),0UTMT(2333)

(b) Copy 9-track tape to a new 9-track 

INMT (2333),OUTMT(?,COPY2333)

(c) Copy 9-track tape to a non-standard 7-track 

INMT (2333),0UT7T(TEMP(NONS))

Tape ownership

Non-standard and Xenotapes can be copied without difficulty.

Worktapes must be DEADed and then accessed by tape serial number as insecure tapes.

Owned tapes must either be trapped to the issuer of the job, or run under his username (hence *NM parameter).

Tapes belonging to a user, which are in a subdirectory, will have to be accessed using DY to select the required directory.
