I got in trouble recently with an enormous script I stored in a field 
(thousands of lines) on the
understanding (false) that things were more economical like that rather 
than duplicating the
script across 15 buttons. Because the script was stored in a fld it had 
to be compiled dynamically everytime
it was needed by a "DO" command; but it DIDN'T, so DON"T store scripts 
in 'funny' places and DON'T
use "DO' commands; they are very nearly fatal except for little1 or 2 
liners - at which point the 'economy'
argument collapses.
