VMS Help PASCAL, Data Types, Ordinal, INTEGER Types  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  Compaq 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.

• Standard Int Radix
• Nonstandard Int Radix
