Constant indicating current revision level of the Object Dictionary.
$ODRevision and $ODVersion identify the current release level of the Object Dictionary. $ODVersion changes the actual format of the dictionary changes. $ODRevision changes when the standard contents of the dictionary (as supplied by ZIMINIT) change. You can use these constants in your own code or tools if they are dependent on a specific version of the Object Dictionary. For example, a change in $ODVersion means that you should check any utilities you have written that access the Object Dictionary. At the very least, you must recompile these programs.
