Re: Open Explicit -vs- Open Implicit

Jerry,

It's whether you use the OPEN op-code (explicit open) or whether the
program opens the file automatically (implicit open). By coding the OPEN
statement you *are* explicitly opening the file.

So basically, there's no point in doing a MONITOR for 1216, since an
implicit file open is performed when the program is initialized, before any
user code gets executed.

I know the different between implicit and explicit, but what is the
difference in RPG? Does it have to do with whether or not the EXTFILE( )
keyword is used on the File statement? Just got curious and couldn't find
it in the manual.
