[MacPerl] print chars to STDOUT without \n?



hi,

i want to print one char at a time to STDOUT, but print doesn't flush the 
buffer until it hits a \n.  i seem to vaguely remember that this is 
possible, but i can't figure it out; printf "%c" doesn't work (at all - i 
get a "Argument isn't numeric in prtf" error) - any ideas?

thanks,

alex.
