A computer program, PRP, has been designed to plot any arithmetic combination selected from a set of major and trace element data on a y-x graph. y and x are defined and entered as a program string (y, x) which is interpreted sequentially. Operators (+, -, *, /, (unary), square root, log10, Inc, antilog10, exponential, integer, absolute value, (,),,) and integer or real numbers may be included. Axis lengths and scales are determined by the user. Five different plotting symbols are available.
