[RESEND] Do 'select' should behave like this?

[DervishD]

    Hi all :)

    Try this:

    select ITEM in 1 2 3 4 ; do print $ITEM ; clear ; done

    Enter '1', for example, and see how the list dissapears. You must
press 'enter' to display it again. Any way of solving this? Should I
set or unset any option? It only happens when issuing the clear or
when the executed command clears the screen (for example, try to use
a viewer instead of 'print').

    Thanks a lot in advance :)

Right; "select" only reprints the select list when the user seems to be 
confused about the possible choices.  It has no way of knowing what the
state of the screen is.

Not directly with only select.  You can of course do this:

  while some suitable condition
  do
    select ITEM in 1 2 3 4
    do
      a thing that wipes the screen
      break
    done
  done

    OK, I thought that it was a bug, but this makes sense.
