No, what IBM turned over to RexxLA was Object REXX (OREXX). IBM originally made REXX available for CMS in 1983 and for TSO in 1988, while IBM didn't make REXX available for OS/2 1.3 until 1991.

Which is he using? Do they differ? Is GAAP a requirement? Does . either Rexx support GAAP? Does COBOL? Does DFP? <end> Let me start off by stating: - I don't know what "GAAP" means. - I am fully aware that Dave Clark is implementing code for z/VSE. I didn't have any of the IBM z/VSE publications on my system, so I used citations from the z/OS publication and the corresponding publication regarding the Rexx implementation for Microsoft Windows and Linux. The latter two are produced by the Rexx Language Association and the original implementation was based upon the IBM implementation for IBM OS/2, Microsoft Windows, and IBM AIX. In October 2004 IBM issued announcement ENUS904-207 which stated: . As part of IBM's continued support of the Open Source community, . Object REXX has been provided by IBM to the REXX Language . Association (RexxLA). The code is now available under an open . source project from RexxLA under Common Public License (CPL) V1. . .

There is also an ANSI standard for Rexx (X3J18-199X). The RexxLA implementation is highly conformant to this standard. The IBM implementation on z/OS is somewhat less so (which is kind of ironic, since Rexx is an IBM invention). Today I fetched the VSE/REXX Reference (SC33-6642) from the IBM web site. Its language regarding "Precision" and the "NUMERIC DIGITS" instruction is virtually identical to the citations I used in my post. With respect to the response to my post by Tony Thigpen, advising me to "go back and read all of Dave's posts and and the responses": I have read each and every post since the beginning of the topic started by Dave Clark. I have even contributed some coding examples to try to help him. With respect to clarity, even Dave Clark acknowledged confusion: "But possibly what is confusing is that this thread of questioning is about zoned input which is only indirectly related to the zoned output of the routine I just mentioned." Similarly, Tom Marchant noted his confusion: "I'm confused. Are you passing zoned data in a register? Or the address of zoned data? Or perhaps a binary number?" From my perspective, it is totally reasonable to ask for clarifications from Dave Clark as well as from other contributors to the discussion. Bob
