Is there a way to force the statement

print ".";

to put a dot on the screen immediatly after it is issued, rather
than after the output buffer is full?

Below I explain why I need this, just in case anybody is 
interested.

Thanks

----------------------------------------------

I have a perl program which is divided to stages.  I would like
to print out a dot every time a stage finishes, so that an output
such as

doing...................done

is gradually produced.


My program looks something like

print "doing";
<stage 1>
print ".";
<stage 2>
print ".";
<stage 3>
   .
   .
   .
<stage n>
print "done\n";

Having the entire line printed out only when the program finishes (as
it does now) is not very useful.
