I've not tried IDL 3.5 nor IDL on an Alpha, but in 3.1 on Solaris and VMS then (and here I assume you are working with a /NONEXCLUSIVE menu) the following works:
instat = [0b,1b,0b,1b]
labels=["B1","B2","B3","B4"]
Xmenu, labels, base, /nonexclusive, buttons=buts
for j = 0, n_elements(labels)-1 do widget_control, buts(j), set_button=instat(j)
This will have "B2" and "B4" set and "B1" and "B3" unset.
