I may need to be corrected but I thought that, when you order z/OS, you cannot avoid also ordering Communications Server and that necessarily includes VTAM. I'd be happy to be corrected if this is wrong! Maybe I just misunderstood why you are using the word "ubiquitous" which seems to imply there is an option!

In order to support the OSA/ICC and equipment providing closely similar function, there must necessarily be some way to define a "non-SNA" device address which can be specified with the CUADDR operand of a VTAM LOCAL statement. So, whatever the "hardware definition" code is, IBM *still* supports it. Incidentally what difference is there between "true" and not "true - "false"? - "local non-SNA support"?

... While VTAM is convenient and ubiquitous in zOS shops, if IBM still supports the 3791L (really a 3174-1L), then true local non-SNA support is readily available, and EXCP is (non-noticeably?) faster than VTAM. TN3270(E) software has the drawback that it needs to run on PCs that in turn are a lot easier to compromise than "dumb" terminals. Gerhard Postpischil Bradford, VT
