#1) a) If object, where it will be saved in library?
b) If not Object, how the AS/400 identifies it?

No, it’s not an object. Spooled files are stored in file members in the QSPL library. When output is ‘spooled’, the system creates an entry in a queue object ( an “output queue”) that maintains the identification and the location data. You can use the DMPOBJ command against an *OUTQ object to get an idea of what an entry on an output queue looks like. (Try it against an *OUTQ that only has a couple entries.)

Objects in the QSPL library are intended for use by the operating system and the spooling subsystem. You can usually get away with looking at stuff in there, but you can make a real mess if you’re directly accessing something in there when the system is needing to get an exclusive lock. Use the commands and APIs that are provided for it.

#2) Whats the type of spool file.

Type? What do you mean by “type”?
