A Versatile Tool for Data File Transfer and Manipulation.

Abstract

This document describes in detail a software tool for manipulating data files. The Surveillance Acoustics section at Defence Research Establishment Atlantic has acquired VAX computers over the last few years, and analysis tasks which were formerly done on PDP-11 computers are now being moved to the VAXen. PDP-11s are still used in the atsea data collection role, so some means is necessary of transferring the data files thus produced to the VAXen for signal processing and analysis. PDP-11 data files are typically located on 9-track magnetic tape, so one method of transferring the data would be to read PDP-11 tapes on the VAXen. The software tool described here (a program named TRANSFER) was written, in part, to perform this data transfer chore, taking into account the special formats and header information in the files produced by the PDP-11s. Manipulation of data files already residing on a VAX is also possible using TRANSFER. The program is versatile, allowing the user to choose channels and data segments to be transferred between files with a high degree of freedom. Keywords: Underwater acoustics; Subroutines.
