/*
** READ_ARG -- Read a single argument from pipe
**
** An argument can be as simple as an integer, or as complex
** as a query tree.
**
** Parameters:
** ppb -- the pipe block to read from.
** pparm -- the parameter descripter to put the
** argument in.
**
** Returns:
** none.
**
** Side Effects:
** May allocate space from Qbuf for trees, etc.
**
** Called By:
** readinput
**
** Trace Flags:
** 10.6 - 10.7
