a pds or a member of a pds ?

statements like

Select all

//xxx dd disp=shr,dsn=some.pds.parm(AAA)

or

Select all

//xxx dd disp=shr,dsn=some.pds.parm(AAA1)
// dd disp=shr,dsn=some.pds.parm(AAA2)

I've seen everywhere (they are handled just like any sequential dataset)
but

Select all

//xxx dd disp=shr,dsn=some.pds.parm
or
//proclib dd dsp=shr,dsn=some.pds.proclib

where the program itself decides which member(s) to use ? Those programs usually have calls to some "dynamic allocation" routines or services.
I think we're talking about different things.

Hello,

Those programs usually have calls to some "dynamic allocation" routines or services.

Yup, sure do

My examples are of the simple variety where one or more members is used as sequential input to "something". Kinda as a reply to:

But I'd like to see a batch program that has a PDS in the DD-list and accesses members without "doing some kind of dynamic allocation"
