But this is not aboput a calculator; it is about a computer program laid out 
on paper,
and one in which the syntax checking of the HLL compiler will root out 
mismatched
parentheses in a way that no sytax checking in Forth would root out, for 
example,
an extra DUP inserted into the assembly-like code.
