/* Implementation note: on VMS is it preferable to do real conversions

* DSO_load call will either load, put the loaded filename into the DSO
* (which marks it effectively as "read-only"), and return success - or
* it will fail. VMS needs to work out what to do - otherwise DSO_load
* will always succeed, but leave the DSO looking unloaded (because the
* loaded_filename will be NULL still) and then real loading (and
* setting of loaded_filename) will only happen during the first bind
* call (which should have error checking anyway to prevent you calling
* it on an "unloaded" DSO - thus giving VMS *serious* grief). Richard,
* what do you think? Is it worth having DSO_load() try to find and pin
* itself to a library file (and populate loaded_filename) even though
* it's unecessary to actually do a load prior to the first bind call?
