Re[2]: F9 Command Retrieval

["Eric DeLong"<eric.delong@xxxxxxxxxxxxxxxxx>]

     Put simply, APIs let you do OS400 functions directly from your HLL 
     program. Many times, functions that you write in CL can be 
     performed directly via an API (such as sending messages, checking 
     on the status of a device, sending a document as E-mail, etc..) and 
     will usually perform faster with better features and with more 
     reliability. Think of them as the subroutines that IBM uses to 
     perform OS functions and you'll be on the right track.
     
     Learning API programming can be a real hair pulling experience, as 
     the documentation for APIs is a little cryptic. But once you try it 
     a few times, you'll start getting the hang of it. Watch the 
     magazines for example code to get you started...
     
     IBM supplies some rudimentary interfaces for some of the APIs. 
     These are generally found in library QSYSINC, and contains things 
     like data structures and parm lists.....
     
     I don't have any books here besides softcopy, but I know some are 
     available for API programming....

Okay, everyone has the right to a stupid question.  Here is mine.  I keep 
seeing things about APIs.  I have no idea what you are talking about. 
 Help!

Rajeev,

I don't know if this was previously mentioned, but rather than copying
or scanning the joblog there is the Retrieve Request Message (QMHRTVRQ)
API which provides several methods for retrieving previously executed
commands.  The API can be found in the Message Handling APIs chapter of
the System API Reference and would not require periodic recopying of the
joblog or filtering on your part for non-request messages.
