I skipped a few in the middle, here, but one case where I use do and value
is in lieu of having pointers, something that is not very easily replaced
by an array. Using value and do allow me to write generic routines for
populating forms and updating database tables afterwards, using the field
name

Just now I can't think of an example for *generating* variable names
only.
But there are very simple and important ones for *using* variable
names:
local a1=1, a2=false
