The book "ATOM Business", and its accompanying cassette, describe eleven business programs covering a wide range of different business applications:

ADDUP tallies a column of totals, and provides verification facilities.

LABEL prints multiple copies of labels from a typed address.

WTMS is a general-purpose conversion program, between metric and imperial units, and can be extended to deal with any desired conversions.

DCF calculates whether the best option in a particular situation is to lease or buy equipment, based on the discounted cash flows involved.

SALES maintains a file of sales data on cassette, and provides commands to update and edit it.

GRAPH will print a 'Z' curve of the sales figures from the SALES program, showing cumulative sales for the year to date, actual sales week by week, and a plot of the 3-week moving average.

NOM maintains a nominal ledger, using a printer for an audit roll.

BUDG performs the calculations necessary to divide a financial budget into the correct portions over a year.

EXS calculates an expenses claim, keeping control of the VAT components of each expense.

STD gives the standard deviation for a set of data values.

QUE sets up a simulation of a queueing situation in a supermarket or shop, and gives a pictorial display of the state of the queues as a function of time.

The book and cassette are produced in conjunction with Phipps Associates.
