This is a valid part of a TurboPascal 5.0-program:
CASE n OF
1: p := 7;
2: p := 6;
3: IF x = 4 THEN
p := 5;
ELSE
p := 4;
END
What's wrong?
Well, I guess you spotted it. The ELSE is an ELSE in the CASE-
statement, and not in the IF-statement, as the indention suggests.
And the error is the semicolon at the end of "p := 5".
It bit me yesterday ... I would prefer if the CASE-ELSE had
been OTHERWISE.

Oh well, such is life....of course, you could always invent your OWN programming language and solve the problem quite readily that way! :-) >-------------------------------------------------------------------- >Erik Jacobsen, Computer Science Department, Aarhus University >Ny Munkegade, Building 540, DK-8000 Aarhus C, Denmark +-----------------------------------------------------------------------------+ |Timothy D.
