Since it's true that all it does is store to a temp file and run it, do you think this is any faster then just FILETOSTR() followed by 'DO SomeCode.prg' ? I was hoping it could all be done in memory...

The Exescript is MUCH MUCH faster than
StrtoFile(mycode)
Compile (mycode)
do (mycode)

It's the compile that's slow, at least on our systems. The Exescript doesn't seem to have the COMPILE delay. You can't run a .prg at runtime, you need to COMPILE first.

So I'd be using Exescript() wherever you can.
