Steven Hawkins resolved TEIID-1237.
-----------------------------------

    Resolution: Done

assignment syntax has now been cleaned up.  procedure return/out/inout values can now be accessed from a command statement in a procedure.  however to access out parameters requires the use of named parameters - our old resolving logic ignored positional out parameters, so it would be a breaking change to now require them.  

These values are only available from a command statement.  It would be straight-forward to extend support to loop statements.  To increase usability all around though, we should probably add explicit cursor syntax.

> Teiid stored procedure command or assignment statements do not typically make use of inout/out/return values (the exception is if a resultset is not returned).  It would be better to allow variables to be used in inout/out positions to capture the out values.
> e.g. instead of
> call proc(1)
> just implicitly creating the result set to return,
> a = call proc(1, b)
> would also assign the return value to a and would set an out value to b.
