Re: Overlaying a DS over an entry parm

Simply put - cannot initialize to an unknown address.

The address of the parameter is not known until you are called - it is after 
all the address of the variable in the storage of the caller and can 
therefore be different on each and every call.

You can do what you want by using %Addr to set the pointer within your 
logic.  However - if you are on V5R1 or later a "better" solution is to use 
LIKEDS to describe the parameter itself.

D SRCXFER         PI
    D  SrcFile                            LikeDS(LibFile)

Then the data structure:

    D LibFile         DS                  Based(pNeverUsed)
    D  ObjName                      10A
    D  LibName                      10A

In your code you specify SrcFile.ObjName, etc.
