>>well, I also have VFP9SP1 (I checked VERSION(4) = 09.00.0000.3504), which I re-installed before Xmas. Maybe I did something wrong, because the first example worked with the previous installation quite well. I tried your proposal, which again produced 4 columns instead of 5, but this time the objname column was missing.

>=MESSAGEBOX(class) && Does it give an error?

just as a reminder: I have opened a ClassLib as a table like

use myClassLib.vcx

As far as CLEAR ALL is concerned, the Visual FoxPro Help says:
"... Releases from memory all variables and arrays and the definitions of all user-defined menu bars, menus, and windows. CLEAR ALL also closes any tables, including all associated index, format and memo files, and selects work area 1..."

So after CLEAR ALL neither the table aka ClassLib nor any of its fields are available anymore. Naturally MESSAGEBOX(class) will yield an error AFTER the CLEAR ALL command. It does not after the USE and before the CLEAR ALL.

Sorry,

Hans
