Test if 4 variables are equal

[millisys]

Hi all,

I'm just trying to figure out the best way to check if 4 variables are equal for error checking purposes.

I know I can test each of the combinations like this

if $var1 <> $var2 and $var1 <> $var3 and $var1 <> $var4 and $var2 <> $var3 and $var2 <> $var4 and $var3 <> $var4 then

but I am curious how programmers would format it to be more efficient.

Thank you

Like this

If $var1 = $var2 And $var1 = $var3 And $var1 = $var4 Then   ;all the vars are equal
If ($var1 = $var2 And $var1 = $var3 And $var1 = $var4) = 0 Then ;any of the vars are not equal. - you can use a "NOT" operator over here even.

I'd have the variables in an array and loop through them, exiting on the first false.
