Re: RTNDTA Question

["Simon Coulter" <shc@xxxxxxxxxxxxxxxxx>]

Hello Dave,

I can't test any of these suggestions at the moment so caveats apply.

According to the DDS manual multiple formats shouldn't matter.  RTNDTA is only 
ignored on an EXFMT or a READ 
with an intervening WRITE to the __SAME__ format.  A different format shouldn't 
have any effect.  Are you sure 
the operations are occuring as you think?

One other point, ERRMSG, ERRMSGID, and PUTOVR are ignored if an operation to a 
different format occurs before 
a second WRITE to a format with those keywords active.  Perhaps RTNDTA is 
similar.  If this is true it reduces 
the usefulness of RTNDTA.  I rarely use it because I don't use the same field 
names for the screen and 
database.

Try EVAL ZZ01BIN.  If that doesn't work then dump the RPG IV program and see 
what the variable is called now.  
Although I do recall something about this feature not being available in RPG IV 
programs.

Regards,
Simon Coulter.
