Re: return indicator

I think there is a difference - the RETRN opcode instructs the program to return
to its caller at that instant, whereas setting on the RT indicator will cause
the program to return to its caller at that point during the cycle where the
RT/LR indicators are checked.

So if RT is set on half way through detail-time calcs, the program will not
return to caller until after total-time calcs have been done and LR has been
checked too.

Its a long time since I used the cycle, so I hope I am not missing/forgetting
anything here !

<snip>.... Per my last post:  Is setting on the RT indicator functionally
equivalent
to using the RETRN op code?  Sorry for the error.  Again, thanks for any
help.  <endsnip>

Return Indicator (RT)
You can use the return indicator (RT) to indicate to the internal RPG logic
that control should be returned to the calling program. The test to
determine if RT is on is made after the test for the status of LR and before
the next record is read. If RT is on, control returns to the calling
program. RT is set off when the program is called again.
Because the status of the RT indicator is checked after the halt indicators
(H1 through H9) and LR indicator are tested, the status of the halt
indicators or the LR indicator takes precedence over the status of the RT
indicator. If both a halt indicator and the RT indicator are on, the halt
indicator takes precedence. If both the LR indicator and RT indicator are
on, the program ends normally.
RT can be set on as a record identifying indicator, a resulting indicator,
or a field indicator. It can then be used as a conditioning indicator for
calculation or output operations.
