Category: Operating System and Languages [XB]

This is the original Base Product Standard introduced in 1992, at a time when the IEEE std. 1003.2 was a Draft 11.2 and nearing ratification. It was intended as a transitional Product Standard to encourage migration to the new POSIX-2 standard (ISO/IEC 9945-2:1993 (POSIX-2)). As far as the Commands and Utilities Product Standard is concerned, a product registered as conformant to this Product Standard can be anywhere in the transition path between the XPG3 state and the POSIX standard, but its actual state must be clearly defined in its Commands and Utilities Conformance Statement. Apart from the Commands and Utilities Product Standard, all other aspects of this Product Standard are firmly defined, and are identical to those defined for the Base 95 Product Standard.
