A memory module being fitted into the back of an XM32 |
The memory in the XM32 is in two parts. Internally there is a RAM memory where all variables are stored. Some are temporary and others fixed. We call these Housekeeping, where factors, rates and small tables are stored. The RAM has it's own internal battery to ensure that data is not lost. Values that are likely to change without notice, such as VAT rates and Car Tax are usually stored here together with company specific details like commission rates. These figures may be altered using varying levels of password control. For example, the Area Manager may set commission rates for the user whilst VAT and IPT may be set by the user.
The second memory is the module that is plugged into the back of the XM32. This has a capacity of up to 1M byte which does not sound much these days, but thanks to the extremely compact SquareBasic program code, most of our Clients get all of their products into 128k bytes or less. The module is erased by Squarezone using ultra violet light and stored ready for our Client's use. Once a program has been produced or altered or new data tables have been incorporated, the module is programmed, eight or sixteen at a time. They are then despatched to our Client for distribution to their sales force. We also distribute modules direct to the user where required.
