Hi,
FALSE AND ERROR is FALSE ? That cannot be !
I disagree.
FALSE AND ... whatever is FALSE since whatever is never evaluated.
FALSE AND ERROR has to be ERROR !!!
Definitely not.
The first condition (a<>0) is NOT met and so, in any other programming
language I use, the second

As a=0 at line 30, there is an "ERROR IN EXPRESSION" in the "if" condition
And there is no way to put this expression to "true" or "false" as there is a
big BIG "ERROR" !!!

That language definition (if it exists, I don't know) would only matter for
functions - simple comparisons that have no side effect would be fine to simply
omit.

Because it's part of the language definition.

Neither Turbo nor QLiberator do short-circuit evaluation.
C68 does.

The first condition (a<>0) is NOT met and so, in any other
programming
language I use, the second condition isn't even tested, as the result
will be "false" anyway because of this.
Standard BASIC approach is to evaluate first expression, store the
result

What, I can't expect perfection in 48 K (and SMSQE is much larger)?

Yes, its dumb, but the problem has been there since the day day dot. So
suck it up and work around :)

Hi all,
Just a rant about the SBasic AND operator.
Suppose this:
10 a=0
20 b=10
30 if (a<>0 AND b/a=5)
40 do_something
50 end if
Run it and what happens?
You get an "overflow" error at line 30.
You get this error because it is trying to evaluate the second condition
(b/a) and failing as
14 matches
