Actually, createVariable is useful if you ever need to dynamically
"mass-create" variables through a loop (though I am not sure why you
wouldn't just use an array at that point). What I am looking for would be a
function that would allow me to specify a string as an argument and return
the value of an already existing variable that matches that string.
Something more like:

  $i = 0;
  while ($i < 11)
  {
    $foo = "$client_" + (char) $i;
    $value[$i] = extractVariable( $foo)
    $i = $i + 1;
  }

extractVariable() would be a Lite function that returns the value of the
string representation of the variable.
My form would have a number of fields named client_0 through client_10 and
that code would let me assign the values of those fields to the $value
array. I would prefer that to the overhead of some symbol table that
contained every field from the submitted form.
