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.

I set test_value = to itself as a dummy argument.
It is not necessary.

I think it is quite easy. Instead of the 'type check', that aborts with a=
n
error message in ex.err, you should make it a function, that returns (for=
instance) -1 when there is an error in the input. Put this function in a
while loop:
function check_for_error(object input)
-- code goes here:
-- if error in input then
-- return -1 (BAD)
-- else
-- return 1 (GOOD)
-- end if
end function -- check_for_error
-- main routine -------------------------------
integer error
error =3D -1
while error =3D -1 do
-- get input
-- check_for_error(input)
-- if error =3D -1 then
-- error handling routine(s)
-- end if
end while
-- loop will be left with valid input
Hope this helps
