RE: Multi- Occurrence Data Structure

I created a service program that returns a data structure array as one
of the parameters. I wrapped it in an external stored procedure for
return as an SQL result set. At V5R3, the program would not compile when
the host variable on the SET RESULT SETS clause was a data structure
array (I believe it was global without the QUALIFIED keyword specified
or implied, but it was several months ago). However, it did compile with
a MODS as the host variable. Did V5R4 fix this? Did I miss something? Or
is this the exception that proves the rule "Everywhere you use MODS you
can use datastructure arrays..."

Curious,
Roger Mackie

2) Everywhere you use MODS you can use datastructure arrays, but not the
other way around. E.g. you can't explicitly define nested MODS in RPG,
as you can with datastructure arrays. So instead of using two syntaxes /
concepts for the same thing one could better "standardize" on just one,
being datastructure arrays.
