You can use following sequence to learn: 1) Indirect addressing via memory (16-bit pointers) 2)Indirectaddressing(32-bit pointers) area-internal via memory 3)Indirectaddressing(32-bit pointers)area-crossing via memory 4) Adress registers AR1, AR2 5) Indirect register addressing (32-bit pointers) 6) Working with In/Out variables of complex types 7)UsageofAR1,2byoperatingsystemofCPU 8) Constructing/parcing of data types POINTER, ANY (48-bit pointers,80-bit pointers) // - quite complexthings,youshouldhavegoodbase(i.e.1-5)toworkwiththem.

I find these documents a very useful. Are they generated only for internal use fo Siemens or can they be made available to the"Siemens User Community". It would really good if these documents could be made availble either in the Product Support section, Applications & Tools or in Forum.
