Many thanks Nadya but PDM is not what I'm looking for. Buy analysing I mean going through code and find all lines which can be improved on some way. I think I'm talking about code optimiser rather than analyser then ))))). E.g.:
- if object is created but never used in code
- LOCATE is used but LOCATE NOOPTIMISE could improve performance

I know that such tool exists for VB and I'm just curious to find something similar for VFP.
