>I found the problem. My logic was not correct and certain prgs where using editsource() instead of modify command. Thanks for pointing me in the correct direction.

Another possible source of information on what you've been doing is the ref*.dbf in your
c:\Documents and Settings\{username}\Application Data\Microsoft\Visual FoxPro 9\RefFile.DBF (also refdef.dbf). The trouble is that the info in these files is stored in binary memos - good luck deciphering those.

I've found that when I run out of space on my C: partition, the quickest way to reclaim space without any ill effects is to zap the refdef.dbf - it helps to have it, but doesn't hurt if you don't. With code references, document view and good naming of pieces of code, it's easy to find what you may be looking for.
