Ok, so Maarten defended my example while I was away from my home base.
Thanks for that.
Stata gives you a note after each -replace- operation, like "(2 real changes
made)", which provides you with a hint whether your operation succeeded.
After the first three -replace-, Stata will report "0" changes, while the
last three, with the -float()- function present, will lead to the
appropriate number of changes.

Hey Martin. Thanks so much for your time. I hate to take more of your
time but I really do not understand what you mean below: where you use
the inp command, can you explain what you mean there??
But note the difference that the -float()- function does make to the
