I would also recommend using semicolon as a statement terminator rather
than a separator.  Modula-2 specifically allows the extra semicolon
so that this may be done.

            IF TRUE THEN
              J := I + 1;
            ELSIF NOT TRUE THEN
              J := I - 1;
	   .....

Although it isn't syntactically required, it results in a more uniform
appearance to the code.  Also, if a substantial block of code follows
the IF and you latter add more statments to the block, it is easy to
miss the omitted semicolon when the J:=I+1 is no longer the last
statment of the block.

Admittedly this is a matter of style (read: personal preference) and
I do not claim that the form omitting the semicolon is in any sense
"ugly" or anything like that.
