RE: RPG Indicators

["Hatzenbeler, Tim" <thatzenbeler@xxxxxxxxxxxxx>]

Mainly because your trying to avoid the use of a goto statement, and place
it within a logical loop, you could easily code like:

dow 1=1
read
if %eof
leave
endif
enddo

or, what i normally do.

d Done            s               n   inz(*Off) 

c     *start        setll     pmpreqd                   
c                   dou       done                      
c                   read      pmrreqd                   
c                   if        %eof(pmpreqd)             
c                   eval      ReqCtl_SflEnd = *on       
c                   leave                               
c                   endif                               
c                    ....
c                   enddo

And this will loop forever until you hit the LEAVE command.
