Hello Some Slacker,

I have similar thing I am doing to keep track of Movie inventory.

rec[1]=movie_num
rec[2]-title
rec[11]=history
rec[11][1]=date
rec[11][2]=item--purchased ,sold,rented,traded etc.
rec[11]3]=amount
--as you can see record 11 could be of any length. A movie could be bought,
--sold, bought back again ,rented 3 times and then sold again. A long history.

  The best way to keep track of everything is with an index.
  For my index I use movie number.
  Maybe you could use something like transaction number.
  Make that rec[1].

--add a new movie
database=append(database,rec)
index=append(index,rec[1])
--find a movie
a=find(movie_num,index)
title=database[a][2]

So on and so forth.
There are A lot of database programs in the Archives you could look over.
But for your purposes it would be best to construct your own.

Starting off with transaction num being rec[1]
and building on that.
