[A library of procedures in LOTUS 1-2-3 for the rapid processing of laboratory data]

A series of MACROS have been drawn in order to eliminate the steps between the initial data and the final results. There are described more than 20 groups of MACROS for general mathematical operations and statistical works (t and chi-square tests, which are interpreted). Besides mentioning the input data, there are given details on reading the output results. The method described here can be used to easily develop this MACRO library, by adding new MACROS which should respond exactly to the specific data processing operations of each laboratory. Examples with data from the virology laboratory show using of these MACROS by any user, even those having a minimum knowledge about LOTUS 1-2-3 or about data processing.
