[TxMt] DIALOG1 or DIALOG2

[Hans-Joerg Bibiko]

Hi,

what is the best way to detect whether only DIALOG1 is available or  
DIALOG2?

Up to now I would do this by checking whether the shell variable  
DIALOG_1 is set. If yes I can use DIALOG2 features, if not I have to  
use DIALOG1 syntax.

But I do not know whether there will be a change in the near future?

Thanks,
