SYMPOSIUM PROCEEDINGS 1970 The aids to easy and accurate punching are twofold. For as many programmes as practicable, proformas are prepared whcre card columns arc idcntified and the entries to be made in each group of columns corresponding to the value of a variable are clearly defined. Fig. 3 gives a typical proforma used for the closed circuit respiration chamber programme, CCRC3. Note that the decimal points are not punched but are clearly marked on the proforma. ,4s mentioned above, a programme VIEW may be applied to any data so that a print-out is obtained of the data punched on a deck of cards. This is particularly uscful for large decks of cards which are to be processed by lengthy programmes, as it prcvents unnecessary waste of computer time. In recent months we have noted with the increase in proforma use that an increasing proportion of punching is carried out by mcmbers of Biometry staff. Currently a scheme is being developed to process all the pig hcrd records by computer, and there is a throughput of about 3000 pigs annually. If this is successful the scheme will be extended to the other farm animals, in which event we shall probably increase our strength by one punch operator and shall then do virtually all punching within the Biometry Dcpartmcnt. If this happens it is quite possible that a change will be made to the use of punch and verificr.
