(HP-97) … Programs for Use in Benthic Ecological Research

[SlideRule]

An extract from HP-97 Computer Programs for Use in Benthic Ecological Research, Government of Canada (Fisheries & Oceans), Biological Station {Saint Andrews N.B.}, Report No. 1742, Dcember 1983

ABSTRACT
Nine programs for use in ecological research, particularly in benthic ecology, are presented. Each program is recorded on a magnetic card compatible with the HP-97 and is available from the User's Library. Four new programs have been written and full documentation for each is recorded in this report. In addition, two modifications of existing programs (ATP analysis and growth) and an aide memoire for production calculations are presented.

RÉSUMÉ
Le présent rapport contient neuf programs pouvant être utilisés dans des recherches écologiques, en particulier en écologies benthique. Chaque programme est enregistré sur une carte magnétique convenant à l'ordinateur HP-97 et qu'on put se procurer à la magnétothèque des utilisateurs. Quatre nouveaux programmes ont été rédigés et nous donnons ici la documentation complète pour chacun de ces programs. Nous présentons des plus deux modifications apportées à des programs existants (analyse ATP et croissance) et un aide-mémoire pour des calculs de production.

INTRODUCTION
The need to analyze field collected data, experimental results, or chemical/physical measurements frequently involves the use of complicated or tedious mathematical computations which are prone to errors when performed by hand. The desk-top calculator manufactured by Hewlett-Packard (HP-97 or HP-67) provides an economical means of avoiding tediousness and improving the accuracy of analytical computations.
The HP-97 has a printer which provides hard copy on pressure sensitive paper and a program reader capable of storing a computer program prerecorded on a magnetic card by making the appropriate series of key strokes on the calculator. The magnetic card programs can readily be copied by the HP-97. In addition, Hewlett-Packard runs a Users' Library of contributed programs.
It is the purpose here to list the programs available from the Users' Library which are of potential use in aquatic, particularly benthic, ecological research, and to fully document programs written by us for this purpose. The number preceding every program listed is the order number and by reference to it the program can be obtained …
