Yes, they're both bound calls.  (As long as you don't specify ExtPgm or 
*JAVA, it's a bound call -- in fact, you don't even need ExtProc, bound 
calls are the default.  You only need ExtProc if the procedure name 
doesn't match the prototype name.)

No... this ability has existed since RPG IV was originally released in 
V3R1.  In fact, subprocedures didn't exist until V3R2, so in V3R1/V3R6 
the only way you could use ILE features in RPG was to call a main 
procedure.

Folks have referred to this as "calling a module" (which isn't really 
accurate, but it's commonly used).
