Help to get a write problem fixed

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

Ok....here is the code for writing records to a file...which i will use for a porogram..The only problem is that every time i run it, it deletes all the previous information in the text file. 
if n e one can help me with this i will be really grateful.

-=code starts here=-

var stream : int
var d_city, a_city : string
var dist : string

open : stream, "database", put
assert stream > 0
loop
    put "Airport Database Creator"
    put "Please enter the name of departure city or put 'stop' now to Quit "
    get d_city : * 

    exit when d_city = "stop"
    put "Please enter the name of arrival city"
    get a_city

    put "Please enter distance between ", d_city, " and ", a_city, " ."
    get dist
    
    put : stream, d_city
    put : stream, a_city
    put : stream, dist

end loop
close : stream

-=code ends  here=-

*it will generate the text file once u run it.

yes, it's suppose to delete the file once you output to it new items.

there is a tutorial about this, in the tutorial section, forgot the link, but it should be a sticky.
