[asterisk-users] Dial() M parameter in

I can't figure out what syntax to use with the Dial() "M" parameter
for the AEL parser to interpret properly.  Creating an AEL 
macro named "macro-screen()" partly works as a hack, but it must
not turn into a gosub properly, so I get warnings about the "return;".

  Dial(...,tgM(&screen)) with the ael macro named "screen" does not work
  Dial(...,tgM&screen) with the ael macro named "screen" does not work
  Dial(...,tgM(screen)) with the ael macro named "screen" does not work
  Dial(...,tgM(screen)) with the ael macro named "macro-screen" partly works

Is a more correct or otherwise better way to do this in AEL? Is there
some other solution? The other followme examples I've found all have
different behaviors than I want. I'm not looking for the caller to
be prompted for their name or anything, and I don't want the followme
connect to happen unless the cellphone user hits a "1" to accept the 
call, or other key to ditch the call, otherwise cellphone voicemail 
gets the call.


context inbound {
    2155551234 => Dial(SIP/1234 at cme&local/102 at internals,18,rt); // screen these

context internals {
    102 => {
        Dial(${CELLPHONE},30,tgM(screen)); // cellphone user gets prompted
        jump s at general-menu;	// jump to IVR menu if call not accepted

// play message to cellphone before connecting inbound call

macro macro-screen() {    // hack
    if( "${ACCEPT}" = "1" ) {
    } else {
    return;   // I get AEL complaints regardless of whether this is here or not.
