well, I was hoping for an answer out of the FPC community
what FPC does to the different codings, so that the users can
get some guidelines out of it (for example: common subexpressions
in locigal expressions are not eliminated, so it is better to use the IN
or maybe the other way round). My mails were meant to motivate this :-)
but so far only suggestions how to optimize at the source code level.
(and of course: because FPC is sort of inspiration for my work,
I would like to see what FPC does in this cases and to compare it
with what I have)
Sorry about that ...
