[DGD]mappings, use of.

That is quite possible.

Well Im thinking it may not be getting set.  Erm the value of the mapping
that is.

Here it is, I apologise for the spam.  If you meant send it privately Marc,
I
apologise doubly.
This is my beginning at an attempt at replacing the social_d.c in the
Melville mudlib that Ive been working on and rewriting.
Note it dont do much so far :)  Just the whole mapping thing confused me
before I got any further.  BTW Ive never used restore_object() or
save_object()
before so am not sure I got the right idea.

   <cut out my huge comment and explanation>

   socials_wt is the socials with a target,
   socials_wot is the socials without a target.
   adverbs holds the list of adverbs.

mapping socials_wot ;
string  *adverbs ;

    /* If socials file doesnt exist, or there is some error
       in the variables stored, then initialise
       variables so we dont get some sorta horrible
       error.

        Just given them values for test reasons.
