SAS/SHARE User's Guide

Numeric Architectural Groups

The following lists show the hosts on which SAS/SHARE software runs. The lists are grouped on the basis of like numerical representation. No numeric (floating-point) conversion is required in communications between any two hosts in the same group. When two hosts in different groups communicate, numeric conversion is required, and the restrictions and limitations concerning numeric conversion apply.

The IBM System/390 format hosts are:

CMS
OS/390
VSE
Note: VSE is a Version 6 host only.

The IEEE-format, standard missing-value hosts (big endian) are:

AIX
HP-UX
Macintosh PPC
Macintosh 68k
MIPS ABI
OpenVMS Alpha
Solaris
SunOS
SGI

Note: Macintosh is a Version 6 host only. [cautionend]

Actually, some conversion of numeric data is necessary between some of these hosts due to different byte-ordering or alignment requirements. However, because they all use the same number of exponent and mantissa bits, loss of precision or range does not occur.

The IEEE format, standard missing-value hosts (little endian) hosts are:

Compaq Tru64 UNIX (formerly Compaq's DIGITAL UNIX)
Intel ABI
IABI

The IEEE format, PC missing-value hosts are:

OS/2
Windows NT
Windows 95
Windows 98
Windows 32s
Note: Windows 32s is a Version 6 host only.

In a class of its own because of its unique numeric representation is:

OpenVMS VAX
