>>Do it any number of times. You'll see that it writes a .rmp file containing just your command (no you can't open it but check the size), and a .fxp of the same file. Then it deletes both. So it's a strtofile(), compile, do, erase two files. Every time. You can check your temp folder while it's in the debugger.
Agree- this is a powerful feature, but it's not quick. VFP's runtime interpretation remains a very nice feature in 2016, but the antique EVAL() or even & keeps me happy. ;-)
"... 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
