new here, a few questions

Hello,

I stumbled on Plua just last week and now found my way here.  It will
take some time to learn the syntax and try all the Palm-specific
features, but that's the fun part. :)  In the mean time, may I toss
out a few newbie questions?

1) I see that it's possible to access the SD Card with vfs0: ...but is
it also possible to access the DBCache area of RAM?  If not, might
this be a planned feature, or is there some technical hurdle?  For
example, I'd like to write a script that does some
processing/cataloging of the photos in the "Photos & Videos" directory.

(This isn't a Plua question, but when researching DBCache I found
several references stating that RAM could hold only .prc and .pdb
files.  As I can see several .jpeg photos staring back at me, I'm
guessing this applies only to normal ram and not to DBCache?)

2) I'm not so much interested in writing applications as writing
GUI-less helper scripts that run "in the background".  I compiled a
demo from the manual that creates a new .pdb file.  Each time it runs,
it generates a white screen for a few seconds, and the screen that
follows isn't necessarily what I was previously viewing.  I know
something about multitasking (or lack thereof) in Palm OS, but is
there a way around this specific problem?

3) By the time you read this, maybe I'll have found it in the manual,
but how do I launch an existing "appl" file with Plua?  Does it matter
where the program is located (ie. in the ROM, on the SD card, etc.)?

Thanks for the help...and many thanks for Marcio for Plua!
