/**
 *  INSET     In Set Macro
 *
 *       INSET receives two (2) numeric parameters. The first (set)
 *       is a bit map for a set, with each bit being a flag which
 *       indicates if the number corresponding to the bit's position
 *       in the word is in the set. The second parameter (number)
 *       is a number which must be in the range 0 to 31. The macro
 *       returns 1 if 'number' is in 'set', 0 otherwise.
