A generalized program in Hewlett-Packard BASIC for creating, editing, and printing out data files for geochemical applications

identified and explained, without interruption of the program operation. Data files are stored in 5000-word files on standard Hewlett-Packard data cartridges, so that each cartridge can hold over 30 data files totalling over 50,000 entries. Instructions for use of the program (appendices I and II) are stored as a separate program requiring a 5000-word file on the program cassette. Because this instruction program can be accessed by the main program, the file number for this program must be contained within the main program. As listed in the appendices, the main program is in file 1, track 0, and the instruction program in file 2, track 0. These may be changed by changing the values specified in line 440 of the main program (appendix III), and lines 30 and 1740of the instruction program (appendix II).
