An interactive program, ALLCAL, has been developed at Los Alamos Scientific Laboratory (LASL) to calculate the results of spectrochemical measurements of impurities in production samples. The program generates a working curve from input data of standard samples to calculate the impurity concentrations. ALLCAL permits use by individuals with minimal programming experience/ it is truly interactive in providing periodic means to edit, modify, and change incorrect data that might have been introduced through various human error factors affecting any computer program, without the need to terminate and reinitialize after such editing. The program can be used as a research tool to manipulate data with minimum effort and eliminates repetitive input data from its operation. It also provides the spectroscopist a comparison mode to evaluate the effect of the use or nonuse of a given internal standard. ALLCAL accepts either optical density or percent transmittance data from photographic plates and films. The program is written in BASIC language for a minicomputer with 28,000 octal words of core memory and has been shown to be adaptable to another computer system with slight modifications. (auth
