/* Load parameters.
*
* To add a parameter:
*
- * 1) add it to the global or section structure definition
+ * 1) add it to the global_vars or local_vars structure definition
* 2) add it to the parm_table
* 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
- * 4) If it's a global then initialise it in init_globals. If a local module
- * (ie. section) parameter then initialise it in the sDefault structure
- *
+ * 4) initialise it in the Defaults static stucture
