Not to mention....

You shouldn't have any user variables or constants with a name that begins with SQL.

Consider anything SQLxxx as reserved words for IBM's usage.

Just in the interest of combating the combater. :)

Actually, "if SQLFound" shouldn't compile - SQLFound is not a boolean
expression. At best it would have to be something like SQLSTATE =
SQLFound. Also, SQLFound is the wrong name; it should be SQLNotFound.
Not busting Aaron's chops, just showing that making code pretty isn't
always the answer, either.

On a more serious note ... I've never really liked the way RPG
implemented embedded SQL. I would far prefer to have first class
functionality for SQL instead of the pre-compiler 'hack' (as I see it).

In RPG's defense, the syntax for embedded SQL goes back a long way; I've
seen papers from the early 90s on embedded SQL in C, and the syntax is
exactly the same. Now, if your complaint is that you want all the logic
of the SQL precompiler built into the RPG compiler in such a way that
embedded SQL directly generates binary code, rather than acting as a
macro pre-processor, I can sympathize with your position, but that won't
change the ugliness of the embedded SQL syntax.
