Table E-4 HP FORTRAN 77/XL Equivalents of SORT-MERGE/XL Data Types

 SORT-MERGE/XL Data TypeHP FORTRAN 77/XL Equivalent
0byte (character)CHARACTER*n
1twos complement (integer) 
 2-byte (short integer)INTEGER*2
 4-byte (integer)INTEGER*4
2HP 3000 floating point 
 4-byte (real)REAL*4
 8-byte (double precision)REAL*8
3IEEE Standard floating point: 
 4-byte (real)REAL*4
 8-byte (double precision)REAL*8
10CharacterCHARACTER*n

 

NOTE: The variable n refers to an integer number.

Floating point data may be stored in HP 3000 or IEEE Standard format:

  • IEEE Standard floating point data is the default MPE XL NM (Native Mode) floating point format.

  • HP 3000 floating point data may also be created by explicit specification in NM. HP 3000 floating point data is the default in MPE XL CM (Compatibility Mode) or on an MPE V-based system.
