Why do these strings compare ?

[tcurrier]

Can anyone tell me why this expression turns out 'true' ?

str1 = '1234567891'
str2 = '1234567890'
if str1 = str2 then
say "they're equal"
else
say "they're not equal"

If I compare 2 strings with lengths between 1 and 9, and the last character is different, it's always false. But when I use strings with a length of 10, it turns out true.

Did I miss something somewhere ?
Thanks....

Looks like I needed the 'numeric digits' clause.

Using 'numeric digits 10' worked..

This operator('=') might take max of 9 digits for comparision. try this operator '=='(Strictly equal) which give you the expected result.
