This problem has a very simple solution, but the cause is not very
obvious. I've already sent the solution to someone before with the
request
to forward it to cla, but he didn't do this. So please forward the
solution.

You have to read the RM about Text_IO very carefully.

  get(number);

reads as many characters as can be interpreted as a whole number and
converts
this to the result type. Any other characters stay in the input stream.

So e.g. if you input "123.45", you will get "number=123", the next
"get_line(name, last);" will return ".45..." and any characters until
EOL or
name'last is reached, whatever occurs first.

So if you write

  get(number);
  get_line(name, last);

and enter on you keyboard

1234<return>

"get(number);" reads 1234, but leaves EOL, which is then immediately
read by
"get_line(name, last);", which will return "name" empty (unchanged) and
"Last=0".

This is quite confusing sometimes even to experienced programmers.

I hope this helps to let you sort out the solution of your problem.
