Thank you. Now I understand it.

If you want to spawn things, you just assemble a command (IDL or not)
into a string, and give that to spawn.
If it is to run a savefile:
spawn,'idl -rt=whatever.sav'
You may or not want to capture the output of the command, with spawn's
arguments.
But it does not have to be a savefile. You could do
spawn,'idl -e "print,acos(-1d0)"'
Or run a batch file:
spawn,'idl something.pro'

This may give a taste of how to do things with the bridge:
obridge=idl_idlbridge() ;make the bridge
obridge.setvar,'x',dindgen(1e6) ;put something into a var called x in
the bridge
obridge.execute,'for i=0L,3e2 do yb=cos(x)',/nowait ;do some stuff in
the bridge, asynchronously
print,obridge.status() ;find out if the bridge is done
; 1
;(do some stuff here while the bridge is busy)
print,obridge.status() ;find out if the bridge is done
; 0
y=obridge.getvar('x') ;get a variable called y from the bridge
obridge.cleanup ;destroy the bridge when done

Ok, thanks. Can you give an example? Or in other words :)
_=(replicate({c=call_function('PLS_PAULO_GIVE_ME_SOME_EXAMPL ES',/
VERBOSE},indgen(10))).(0)
Thanks

You can spawn a call to idl that uses a sav file, but the sav file
must be complete. It does not seem to make sense to pipe a sav file.
Or you can use an idl_idlbridge to make a new session, and communicate
with it through the bridge object.
