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.

Nathan.
