Scott,

>>I wish to close ALL tables, regardless of what data session they are in.

There is ASessions() in VFP7. In VFP6 I did:

PROCEDURE ReallyCloseAllData
LOCAL lc_WasError, ll_GoOn, ln_Tables,  ln_i
local array la_x[1,2]

lc_WasError = on("ERROR")

on error ll_GoOn = .F.

ll_GoOn = .T.

set datasession to

for ln_i = 1 to 999
    ln_Tables = aused(la_x, ln_i)

    if ! ll_GoOn
        exit
    endif        
    set datasession to (ln_i)
    close data all
    close data
endfor &&* ln_i = 1 to 10

on error &lc_WasError

set datasession to 

ENDPROC
