Oscar ,

You should post a little sample of your code.

Some weeks ago I got help from Sergey because I posted my sample like this:

lcVar = ""
lcVar = NULL
lnExec = SQLEXEC(lnH, 'Exec sp_test ?@lcVar')


* In VFP9
lcVar = CAST(NULL AS char(7))

Final answer, it seems to be a VFP 8 bug, it works fine with VFP 9
