Computer routines designed to determine if a song already exists in a song file data base are described. Written in FORTRAN IV, SONG FILE DATA MATCH compares the note sequence of songs in the data base and the one to be added to it. Information is then presented to the user which analyzes the sequence of notes and compares them to other songs. This document is intended to serve as the software documentation for the programs. Included are a program description, data format specifications, program constraints and limitations, and operating instructions. Program flowcharts, program listings, and sample data forms and reports are also provided. (DGC)
