   test_value = test_value
end procedure

I don't understand the utility of " test_value=test_value ".
It makes the function number_as_string2 to be done twice.
Is it necessary ? ... Otherwise a big routine !
Aoh! another question : how can I avoid or recover
the error message in case of a bad entry ?
Thank you for any help.
