>>Anybody using Chen's compiler? Is everything ok? What's the cost?
I've used it since 2010. Works fine, but watch out if you use macro substitution or EVAL() of strings with variables, since variable names get obfuscated unless you exclude them in the options. Cost is a small annual fee that I would need to look up but if you ask Chuanbing, he is very responsive.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
