RE: Compiled Programs Under V5R4 - Work in V5R3?

Your comment is mostly right.   However, there are times when features
are allowed back.   From the precompiler standpoint, enhancements where
the precompiler is finally supporting a feature that has been in the
compiler for a while will be allowed to a previous release.
For the precompiler enhancements that are because of a new SQL statement
or a new compiler feature, those will not be allowed to a previous
release.

So, you can change your source on v5r4 to have SQL statements
in free format and precompile it with TGTRLS(V5R3).  The program will
run on v5r3.

The only way to make the progam backward compatible is to compile with
TGTRLS(V5R3).  Unfortunatly, this will have the effect of not letting
you use any features not supported by the V5R3 compiler .... including
Free Format SQL.

Hi All,



Within the next month we will be taking delivery of a brand new 520E to
replace our aging 720 box. I just finished reading an article on IT
Jungle that v5r4 will now allow SQL statements in free-form (about
time!).



Now the question - our old 720 will be demoted to a DRP box. I know
that V5R3 will be the highest version of the O/S I can put on this box.
My question is if we put V5R4 on the 520 and V5R3 on the 720, will
compiled programs still work on V5R3? I'd like to move the code over to
the free form SQL, but I will not do it at the cost of having the
programs fail on the DRP machine if the time comes that we need to use
it. I assume I will not be able to modify code on the 720 box if we
move to v5r4, but is that the only limitation?



Any opinions would be appreciated.



Thanks!


Brian.
