to add some more exported procedures to match the needs.
For the implementation you have choosen RLA - again the wrong tool.

Dieter,

You keep asserting that the service program that I referenced in my
original post belongs to me. I have stated several times that it is not
mine. It doesn't belong to me. I wouldn't endorse it. I wouldn't use it. Is
that clear?

I will however post a link to a DB I/O service program that does belong to
me.

Procedure names that begin with "rla" are exported from an RPG wrapper
around C APIs that are exported from IBM's QC2IO service program.

For example, rlaColGet("TABLE" : "COLUMN" : key) is a generic utility that
returns a value, given a table name, column name, and key. BTW, this
function is an implementation of Codd's Rule #2, quoted from Wikipedia as
follows:

"*Rule 2:* The *guaranteed access rule*: Each and every datum (atomic
value) in a relational data base is guaranteed to be logically accessible
by resorting to a combination of table name, primary key value and column
name."

Feel free to provide feedback.
