Hi Matt,
why can you use to-integer
for example
>> a: "1234567890"
== "1234567890"
>> either error? try [to-integer a] [print "Not an integer"] [print
"Integer"]
Integer
>> a: "1234567890aaaaaa"
== "1234567890aaaaaa"
>> either error? try [to-integer a] [print "Not an integer"] [print
"Integer"]
Not an integer
Cheers Phil
