String or Null

4 posts in this topic

Greetings!

I'm puzzled:

$n=0

if ($n = "s") then MsgBox(0,"","n=" & $n & " s")

Why does this comparison gives true?

Actually "s" can be any string.

Thanks for enlightment :-)

Comparison operators (case insensitive if used with strings except for ==) = Tests if two values are equal. e.g. If $var= 5 Then (true if $var equals 5). Case insensitive when used with strings. == Tests if two strings are equal. Case sensitive. The left and right values are converted to strings if they are not strings already. This operator should only be used for string comparisons that need to be case sensitive. <> Tests if two values are not equal. Case insensitive when used with strings. To do a case sensitive not equal comparison use Not ("string1" == "string2") > Tests if the first value is greater than the second. Strings are compared lexicographically even if the contents of the string happen to be numeric. >= Tests if the first value is greater than or equal to the second. Strings are compared lexicographically even if the contents of the string happen to be numeric. < Tests if the first value is less than the second. Strings are compared lexicographically even if the contents of the string happen to be numeric. <= Tests if the first value is less than or equal to the second. Strings are compared lexicographically even if the contents of the string happen to be numeric.
