RE: RPG and SQL Compilers

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

Ahhh, Jon.  When the problem is encountered with RPG3, it is caused by the
number of ODT entries - the number of database, screen, etc fields in the
program.  Those RPG3 JDE programs that blow the compiler have more fields
than will fit into the ODT - seems to me like the limit is 32k fields.  But
this is a creature of the program template and I think that there are two
sizes.  Are you saying that switching from IRP to W-code avoids the problem
or that using a program template that supports more than 32k fields avoids
the problem?  I think that RPG4 uses the larger template version.

(speaking for myself)

 >> Uh, there's such a thing as "too big to compile" with RPG-III?  How so
that RPG-IV is not likewise limited?

Yup - it is not that hard to do.  Both JDE and BPCS include programs that
easily max out.  It happens more often with COBOL than RPG because COBOL
programs tend to have more field definitions (if you have the same field
defined in three different files you have three fields - unlike RPG where
you would have only one).

RPG IV doesn't use MI (it uses W-code) so it doesn't encounter these MI
translator related restrictions.
