Dear David,

I think that the trick is to test for the number of elements returned
from Scope_VarFetch before you assign it to a variable.

;*****************************************************
PRO test01

names = Scope_Varname(Level=1,Count=varcount)
FOR j=0,varcount-1 DO BEGIN
s = n_elements(Scope_VarFetch(names[j], Level=1, /Enter))
Print, 'Fetching variable ' + names[j] + ' with n_elements ' +
string(s)
if (s gt 0) then begin
mainvar = Scope_VarFetch(names[j], Level=1)
Help, mainvar
endif
ENDFOR

END
;*****************************************************

Cheers
Robbie
