A few questions concerning memoDB access:
How limited is Pocket C in this regard?--you can write to the end of a memo but what I'd like to know is:
1) can one program a search and replace feature?
--if so, how limited would this be? I am hoping to create something
like the sed features
2) are the words in each memo treated like fields delimited by spaces?
---or could they be
3) could the database functions like dbwrite() be used in memodb?

Thanks

For speed I would suggest loading the entire contents of a memo into either one big string or an array of strings. When done operating on the text, just write the data back. Sed like operations can be a bit slow in pure PocketC code. There will be a very fast string search&replace function coming in the next PToolboxLib release (It's been already implemented).

Yes.

Yes, the db functions can also be used on the memodb.
