Hi.
I am writing a class on pure Clipper for searching files (including LFN files) on disk. (A simple intermediate demo I have included)
The class is based on well-known DOS functions FindFirstFile and FindNextFile.
My question is about naming conversion. I need a help from english-spoken men. How is better to name an instant variable? I will try to explain my idea.
A class object can be in two state. One state is when there is not any seach method executed yet. And another state is when at least one search method was executed. For example

The first state

DEFINE FILESEEK oFileSeek FILESPEC cFileSpec SEARCH ATTRIBUTE "D" LFN

The second state

DEFINE FILESEEK oFileSeek FILESPEC cFileSpec SEARCH ATTRIBUTE "D" LFN

oFileSeek:search() // i.e in this case at least one searching is done

So how to name a logical variable which will say if at least one searching is done or not?

Here is URL for downloading the (very simple) example.

Vladimir,

maybe DATA lDone ?

lDone = .t. after the search

Thanks Antonio.
However IMHO lDone may be incorrectly understood.
For example, a program searches in cycle all files whish are started with "somefiles*". And lDone may be interpretated that there is nothing more to search i.e we found all we want.
But I would like to say with the instant variable that no any search method was executed. That I only defined an object but did not yet do any real seaching.

lExecuted? lStarted?

Thanks Enrico.
lExecuted is more suitable.
I wil wait a little. Maybe another suggestions will be.

lFinished?

I don't like lCompleted and lFinished on the same reason as lDone.
Also I think over lNew and something similar...
