Tuk asked me to take a look at MSDP and I'm starting to go through the list of items he sent me. I'm interested to hear any other requests/issues with the MSDP implementation.
LOCATION updates will be fixed in the next reboot but I have changed the name to CHARACTER_LOCATION in an attempt to standardize future variable names.
The next reboot will also have CHARACTER_EQUIPMENT which should replace the various WEAR_XXX variables. It includes the VNUM, SERIAL (unique item id), and SHORT_DESCRIPTION along with the same information for clasps and runes.
I've updated the help file and have started moving older variables to an obsolete list at the bottom to indicate which ones will be going away.
