Hi David,

sorry, I didn't mean to pm you.
However, I just figured out you can do this:

PRO my_exit
help, LEVEL=-1, OUTPUT=o
funny_array = strsplit( strjoin( o, ' '),' ', /EXTRACT)
foreach var, funny_array do $
tmp = temporary( scope_varfetch(var, LEVEL=-1, /ENTER) )
tmp=42
exit
END

Neverthe less: Let me know if you find something more elegant!

cheers
