+ * Notes:
+ * 1) I return a string result because most of the functions cannot return any
+ *    normal type anyway (e.g. SYS_DATE, SYS_TIME, etc...), and the few that
+ *    might (SYS_UID or whatever) can just return it as a string - no problem.
+ *    This keeps the function flexible enough to be of good use.
