I am familiar with DLLs on the PC side where you have a single file that contains one or more objects that can be called dynamically (w/o having to be in the .exe file, that is).

Came across DLL's on the mainframe side only recently- I had always thought that DLL's were the same as what I had called Dynamic linking- where I either use the DYNAM compiler option or the name of the called Subprogram is a variable instead of a literal
But I found out that DLL/NODLL is a different compiler option

What exactly is the difference between a DLL and dynamic invocation of a program as I understood?

The DLL and DYNAM options seem to be mutex when compiling.

What I have read of it says that they are really the same but DLL works with C programs and allows long names (but also forces to use PDSE). Rather confusing

See your replies on another forum. It is 'bad form' to post on multiple forums simultaneously. Post on one - then wait a couple of days, and if no suitable solution, post on the next.
