The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.

Well I guess that's the difference between us, you would prefer to write
procedures to fix deficiencies in the compiler, I would prefer the
compiler
was improved.
In this case, it is not a deficiency in the compiler. See next
response.

BTW, the SQL substr() works as expected. The RPG %subst() does not. But
I
don't really want to call into the database just to have it do basic
string
handling.
This makes sense because SQL functions are database-centric while
RPG/LE functions are program-centric. Meaning: SQL functions are designed
with the understanding that they generally operate on data not yet
available to your program. RPG/LE functions are designed with the
understanding that they operate on data already available to your program.
Thus, when the data is already available to your program, you are
expected to be able to determine the characteristics of that data -- such
as its length. You can't know the length (or other characteristics) of
data you have not yet retrieved from the database.
Sincerely,
Dave Clark
