Abstract
A BASIC program named ‘POCO’, a point counting program, has been made for the PC-8201 hand-held computer. The program has following facilities;
1. Mineral names within 3 alphabetic characters are assigned to the keys of F, D, S, R, E, W, V, C, A, and X. The initial mineral names are set as default in the program, although they can be easily changed. The key of I, O, and P are function keys, to move the thin section without counting, to stop and continue counting without movement of the thin section, and to end counting of a thin section, respectively. The other keys are inactive during the counting.
2. The program controls the movement of the thin section through the CMT terminal by MOTOR 1 and MOTOR 0 commands of N82-BASIC.
3. During the counting, the LCD displays key names, mineral names, counting numbers of minerals, and total of countings. The mineral name of last key-in is displayed on the LCD. Display format is adjusted to the number of minerals to be processed.
4. The results of counting are stored in RAM files with the modal percent of minerals.
