Subject: difference between $ and $$ fields
There is no actual rule about fields starting with $, but they tend to be system generated fields. The $$ fields tend to be either temporary or compiled fields. For example, in the properties for a Form shown below, the fields such as $Flags, $TITLE and $HTMLCode are system information about the form, but the $$ScriptName and $$Script_O are generated on the fly when the form is saved.
Unfortunately, there is no rule to say you can create a field starting with $ or $$, so you can’t really count on those meaning anything. It is not uncommon for third party products to use such naming to fistinguish their fields from those actually on the form.
