In touch mode, library functions of one variable (parameter) are called
like standard functions.
If the function needs several arguments, say X1,X2,...,XM, the first one
(X1) is given normally and the remaining ones (X2,X3,...,XM) are saved
in memory locations 1,2,...,M-1 (by key M) before calling the function.
