These idl codes should be added to old AMDA installation in order AMDA-NG to work.

Copy 

     amdalib/* to /AMDALIB/lib
     ddlib/*   to /DDLIB/lib
     predefined/*  to  pro specific for amda-ng don't copy; keep as it is 
     pro/* to   pro specific for amda-ng don't copy; keep as it is 
     templates/* - pro specific for amda-ng don't copy; keep as it is

Normally there should be no interference between old AMDA and AMDA-NG (TO CHECK)
So AMDA installation could be used with old AMDA as well as with AMDA-NG
