A lot of existing code will break if BREAK is added to IF.
BREAK is often used within a WHILE to conditionally break
the loop.

Some other languages allow you to specify the number of
levels of nesting you wish to BREAK by putting a numeric
argument after the BREAK keyword, but I think that this
is unwise.  It seems odd to allow an inner control structure
to affect the processing of an outer structure.

I think that the use of GOTO that has been discussed here
is quite appropriate.

I DO wish that SQR had an ELSE IF structure, however.
