Gas Bill (Spectrum) by J. Ashburner GAS BILL is a useful little program to calculate the cost of keeping yourself warm and well-fed through the winter. The program requires you to enter the number of units used and the standing charge. Of course, our readers would never dream of questioning the great Gas Board computer which sends out the bills, but many might like to reassure their nearest and dearest that the horrible figures are indeed the correct ones. Gas Bill was written by J Ashburner of St Helens on Merseyside, and runs on the 16K Spectrum.
