It should be noted that some functions return not only a function value, but
also return values in variables made available for that purpose. If the
function value is to be ignored, then the function should be called with VOID
or its abbreviation '~'. (In the same way as for the INP() function: the
returned function value may be printed with PRINT INP(2), or ignored with
~INP(2).) When parameters have to indicate addresses, at least 4-byte long
variable types must be used, and coordinate entries must take place in variable
types of at least 2 bytes (word or greater).
