Syntax

 FUNCTION Y=f(X); start end number_of_XY_pairs; GOC;

FUNCTION X=f(Y); start end number_of_XY_pairs; GOC;

 

f(X) or f(Y) are legal mathematical functions of X or Y, understandable by a FORTRAN program. start and end are unsigned real  numbers, and number_of_XY_pairs an unsigned integer. GOC is a legal graphical operation code as defined with BLOCK.
