I have a variable that is valued with "9.10" and I issue the following
IF: "IF VARIABLE version less than "9.5". Its result is false. I change
the IF to: "IF VARIABLE version less than "9.50" and the result is true.
Why?

Even if I change "version less than" to just "less than" it still
doesn't work the correctly.

Obviously I'm not the SB expert here<g> but I think you're comparing
strings, not numeric values. so a string length of 4, for "9.10", is
always going to be greater than a length of 3, for "9.5", at least I
think that's correct?!<g>
By adding the trailing ZERO you force the lengths to match and then
the alphanumerical comparison returns the value you expect.
Or something like that!

Lee - I would agree with that if the IF was checking string lengths but
I assume the IF should be checking the values within the string not the
lengths.

"10" is > "5"
If "9.10" Version Less Than "9.5" is FALSE
"10" is < "50"
If "9.10" Version Less Than "9.50" is TRUE

Each part of the version string is evaluated and compared to the other part.
9=9, 5<10, 50>10.
