Test function with Palindrome entry(Rosetta Code)

[TempodiBasic]

Hi
here my solution to this task http://rosettacode.org/wiki/Test_a_function

Using a well-known testing-specific library/module/suite for your language, write some tests for your language's entry in Palindrome.

Code: QB64: [Select]

1. 'A palindrome is a phrase which reads the same backward and forward.
2.  
3. 'Task
4. ' Using a well-known testing-specific library/module/suite for your
5. ' language, write some tests for your language's entry in Palindrome.
6. Dim palindr As String
7.  
8. palindr = "asdfghjkl78987lkjhgfdsa"
9. If IsPalindrome(palindr) = -1 Then Print palindr; "  is palindrome" Else Print palindr; " NOT  is palindrome"
10.  
11. palindr = "roop123321poor5"
12. If IsPalindrome(palindr) = -1 Then Print palindr; "  is palindrome" Else Print palindr; " NOT  is palindrome"
13.  
14. palindr = "98765abba56789"
15. If IsPalindrome(palindr) = -1 Then Print palindr; "  is palindrome" Else Print palindr; " NOT  is palindrome"
16. End
17.  
18. Function IsPalindrome (Palindrome As String)
19.     IsPalindrome = 0
20.     Dim a As Integer
21.     For a = 1 To Len(Palindrome) / 2
22.         If Asc(Palindrome, a) <> Asc(Palindrome, Len(Palindrome) - a + 1) Then Exit Function
23.     Next
24.     IsPalindrome = -1
25. End Function

Thanks to test and for feedbacks
