OpenVMS Question

[Penney, John]

Dear Listers:
 
Can anyone (25 words or less) explain to me how OpenVMS handles the invocation of an OS RUN command from within PH Quick? My understanding is that, say, Quick Program "A" performs a Run Command "B" statement which would open (spawn) a new session and perform whatever that "B: program is supossed to do. If "B" opened files, database, transmitted data, etc. it could only do so within 'it"s own' session/spawned process? Or am I missing something big here? I am not VMS internals kinda guy, but.....from a logical viewpoint. I'm a performance concerend individual.
 
Just trying to get my mind clear.
 
TIA and Happy Thursday (fly home this afternoon!)
