This investment management system is provided in an attractive purple box containing the master program and a 19-page user guide. It doesn't include the extra cassette(s) you will need to hold the files of data on your shares.
Up to 36 investments (shares, loan stock or unit trusts) can be 'managed' by this program. The program doesn't advise on which investment you should make. Its main purpose is to calculate most of the ratios investors need, and analyse gain and earnings, to aid decision making in investments.
The file will only store information at the time of share purchase and current details. This allows now-and-then comparisons to be made, but you will not be able to get any trend analysis. However, data from a number of points in time can be stored as separate files.
An almost identical version is available for the ZX81.
