Can anyone give me an example of what is meant by this new feature
from the Firebird_v1.5.ReleaseNotes.pdf on page 11.

(1.5) Expressions and variables as procedure arguments
Dmitry Yemanov
Calls to EXECUTE PROCEDURE ProcName(<Argument-list>) and
SELECT <Output-list> FROM ProcName(<Argument-list>) can now accept
local variables (in PSQL) and
expressions (in DSQL and PSQL) as arguments.

Not for sure how to use this or what it means in it's scope of how to
get the maximum use out of it. An example anyone!!
