"Database" by Hayes Publishing (1985)

This is an application modified to work on the TRS-80 Micro Color Computer ("MC-10") using Micro Color BASIC from the author's published source code in the TRS-80 Colour Computer Programmer's Handbook/What Else You Can Do With Your TRS-80 (Hayes Publishing Ltd. Burlington, Ontario, 1985).
