try this, it is only for numbers, but I'm sure you can modify it for your ftp

:
set text size 30
tut = inputstars(0,0,"Choose a number")
set cursor 0,30
print "The number is ",tut
wait key
function inputstars(x,y,q$)
clear entry buffer
repeat
star$ = ""
for t=0 to len(entry$())
if t>0 then star$ = star$ + "*"
next t
text x,y,q$+"> "+star$
until returnkey()=1
repeat:until returnkey()=0
a = val(entry$())
endfunction a
"He will come...the voice from the outer world,
bringing the holy war, the Jihad, which will cleanse the Universe and bring us out of darkness."
