Well, syntax # 1 is much easier for me to read and understand in a program.
Syntax # 2 makes me scratch my head and wonder what is going on.

I have always been one to put complexity into the called procedure rather
than the calling procedure.  The reason being any fixes/modifications would
only have to be done in the called procedure once, and also, once the called
procedure is done they are usually not touched again for a long period of time.

So, I would go with Syntax # 1 definitely.

Syntax # 1:

D myStructure E DS ExtName(myFile) Import

C Eval myReturn = myFunction()

Syntax # 2:

D myStructure E DS ExtName(myFile) Based(myBasePointer)

C Eval myReturn = myFunction(myBasePointer)

I'm trying to determine whether Syntax # 2 is better than Syntax # 1.  They
are functionally equivalent.  Under Syntax # 2, myFunction must explicitly
set myBasePointer to the address of it's version of myStructure.  Under
Syntax # 1, the pointer mapping is implied.

Any suggestions?  Thanks.
