I am trying to make an FTP client application. I want spawn to get value of hostname when user types

proc ftpcon {} {
entry $t.hoste
set name[$t.hoste get]
}
and in other proc i am calling
proc connect_button {} {

spawn ftp

}

Now i want that when i push connect buttonspawn should get the value what user types in Hostname entry.  Can anyone tell me how can i associate these two?

I suggest you use global in a first instance o transfer the data across - I've cut the additions into your code.

proc ftpcon {} {
global name
entry $t.hoste
set name[$t.hoste get]
}
and in other proc i am calling  
proc connect_button {} {
global name

spawn ftp  $name

}

You WILL need to add in error checking if you don't already have it - for example to check that your user doesn't attempt to connect when no host has been specified, or if the host specified does not exist or is not running an FTP service.

Its been two days i started learning Expect and i found it useful... Thanks it works
Can i use this global technique for expect and send commands as well?to get username, password and filepath and connect to that FTP. and how to add in error checking?
