Hello, Martin

Of course you're right - I am aware of advantages of integers. If I'd use them I'd have a lot of headaches to synchronize different databases (which is my case).

Here is the algorithm. I'm sorry, I don't remember where I gathered if from. I believe it was Cetin Basosz, but I'm not sure:

cStrucGUID=SPACE(16)
cGUID=SPACE(80)
nSize=40
IF CoCreateGuid(@cStrucGUID) # 0
	RETURN ""
ENDIF
IF StringFromGUID2(cStrucGUID,@cGUID,nSize) = 0
	RETURN ""
ENDIF
RETURN SUBSTR(STRCONV(LEFT(cGUID,76),6),2,36)

Thank you.
