Hello,
I've been wrting a program that needs to check a few instances before =
executing an if statement. Like so:
if X=3D1 (somecommand) Y=3D2 then
puts(1,"X=3D1 and Y=3D2")
end if
Can I use or for this? Is it as literal as it sounds? Like if this =
variable or this variable equals this, then do the following.(?)
-Thanks
-Thomas

Hi Paul
"and" will evaluate both to make sure x=3D1 and y=3D2
"or" will evaluate both as well, but only one x or y=20
needs to be true to =3D to "puts"
besides, I believe you answered your own question
in "puts" didnt you?

Kat, I think this one is hardly worth two cents ;). Firstly, you did
not bother with the spelling checker, and secondly, I would not worry
about the parentheses, unless it is really a very complex expression.
You see, euphoria is one of very few languages with infix notation
that got the operator precedence right.

Just my two cents worth, use "(" and ")" around all evaluations, it could
save you a headache later when you run into presidences of evaluation.
if ( X = 1 ) and ( Y = 2 ) then
