OK, but what if my script is in a file? source the file(s) again doesn't
work if the script contains commands that create widgets. In other
words, if in your example the proc 'abc' would contain as an example the
command 'button .b -text "Hello"', and then change the command to
'button .b -text "Bye"' re-executing the proc, would give an error: "a
window named .b already exists".
