The use of VisiCalc and VisiPlot software routines for performing calculations and graphing of data commonly encountered in steroid biochemistry is described. These software routines have utility and are relatively easy to use, requiring little or no programming experience. Use of these routines is demonstrated in terms of data processing associated with chromatography of receptor preparations and equilibrium binding analyses. The execution of these software routines is rapid and can result in a considerable savings of time and personnel. These and other generically similar software routines should have the greatest utility in laboratories where the experimental design is subject to on-going change.
