Dear Natural Experts,

It might be a silly question but I am confused and do not have system write now to try it.

I have defined my Variables in an LDA object say LDA1 now I have to pass this complete LDA to a subprogram to be used as PDA.  
Can I use same LDA object LDA1 in “DEFINE DATA LOCAL” of my Program and in “DEFINE DATA PARAMETER” of my Subprogram?

Please advice . Thanks  
Shashank

You can’t use an LDA as a PDA but you can use a PDA as an LDA.

```auto
PARAMETER USING lda /* <-- invalid
LOCAL USING pda /* <-- valid
```

You mean I can use the same Object defined as PDA in my Main Program and Subprogram/Subroutine?

Yes. the calling routine will contain

```auto
LOCAL USING pda
```

and the subprogram/subroutine will have

```auto
PARAMETER USING pda
```
