Programming language: Fortran.
Computer: ICL 1906S.
Operating system: GEORGE IV.

Classification: 4.14.

Nature of problem:
Program RETRIEVE retrieves decks, specified by their catalogue numbers from master library files which are copies of the files described in paper 1. The files may be serial or direct access. The output medium can be cards or listings. Only one person is supplied in one run. Programs CPSN, CPIN, CREC are auxiliary programs, described in appendices 1 and 2, for file manipulation.

Restrictions:
The number of catalogue numbers requested is restricted by array lengths which can be altered.

Unusual features:
Similarly to UPDATE, the program involves character manipulation and requires the same packing subroutines described in C.P.C. 22(1981)59.

Running time:
To retrieve two programs, total length 984 cards, from a magnetic tape program file took 0.03 s mill time. 1950 blocks were read from tape during the retrieval.
