This package provides only two macros viz. \TheKey and \TheValue to define then use pairs of key/value and gives a semblance of hash. Syntax: \TheKey{key}{value} to define the value associated to the key, does not produce text; \TheValue}{key} to insert the value linked to the key. Both arguments of \TheKey are `moving' as \LaTeX{} defines it and we have sometimes to protect them. The author is Yvon Henel.
