Re: Different ways of Ending an RPG program - Request for -Comparitive Study

We all hate general rules, but NEVER use H1-H9 or these 'halt indicators'. 
 They generate a message to the user and it's not a friendly message.

I don't believe that anyone I know of has ever seen or used a RT 
indicator.  I would assume it does the same thing as a RETURN.  So, just 
RETURN.  Perhaps at some stage in RPG's dark past the RETURN code was not 
available.  I suppose we could shoot the first person that wrote:
FMyFile...                             USROPN
C                OPEN  MyFile                                  RT
But that might be a use for it.

Return does leave files open etc, (if lr is not on).  This may be a good 
thing if you plan on calling the program multiple times in the same job 
stream.  In that case you will have better performance.  When you want to 
truly die you can call it again and when some unique condition exists 
(determined by you) it can set on LR prior to executing the return and 
then it will close files, etc.  Or you can stick it in it's own activation 
group and then shutdown that activation group.  Or you can simply exit the 
job entirely.
