This invention relates to a novel crystalline form of 1–4-cyclohexyl-3-trifluoromethyl-benzyloxyimino-ethyl}-2-ethyl-benzyl)-azetidine-3-carboxylic acid, to pharmaceutical compositions comprising this crystalline form, to processes for forming it and to its use in medical treatment. The quantities of the powders are selected so the mixed sample has a predetermined ratio of first powder to second powder. The blackjack game can then proceed normally using the chosen two cards. The system and method provides a means for facilitating both persistent connections and dialup communications between the base computers and the central server system.
