Cross-Architecture Access

Numeric Architectural Groups

Overview of Numeric Architectural Groups

The following sections contain lists of cross-version architecture groups for SAS 8 and SAS 9.2. These architectural groups are valid only for access between the following:

The following lists show the SAS 8 and SAS 9.2 operating environments that SAS/SHARE software runs on. The lists are grouped on the basis of similar numerical representation. No numeric (floating-point) translation is required in communications between any two operating environments in the same group. When two operating environments in different groups communicate, numeric translation is required, and restrictions and limitations are applied.

Note:   For backward compatibility, the following lists include architectures and operating environments that were supported in earlier versions of SAS but are not supported in SAS 9 and later.  [cautionend]

Version 8 Numeric Architecture Groups


IBM System/390 Format Operating Environments


IEEE Format Operating Environments

Translation of numeric data is necessary between some of these operating environments because byte-ordering or alignment requirements are different. However, because they all use the same number of exponent and mantissa bits, loss of precision or range does not occur.


OpenVMS VAX Operating Environment

OpenVMS VAX uses a unique numeric representation.

SAS 9.2 Numeric Architecture Groups


IBM System/390 Format Operating Environment


IEEE Format Operating Environments

Translation of numeric data is necessary between some of these operating environments because byte-ordering or alignment requirements are different. However, because they all use the same number of exponent and mantissa bits, loss of precision or range does not occur.
