VSI Pascal provides the INTEGER, INTEGER64 (not available on all
  systems)   integer  types.   Also  provided  are  the  INTEGER8,
  INTEGER16, and INTEGER32 types, which are used as  synonyms  for
  subranges of the INTEGER type.

  The range of integer values consists of  positive  and  negative
  integer  values and of the value 0.  The range boundaries depend
  on the architecture of the machine you are using.

  The largest possible value of the INTEGER type is represented by
  the predeclared constant MAXINT.

  The largest possible value of the INTEGER64 type is  represented
  by the predeclared constant MAXINT64.
