This is indeed interesting since the problem is seen by three different emulators. I think I need to do more digging. My yellow card has AD as an EBCDIC [. _____________________ Jim Hughes x5586 "It is fun to do the impossible." Quote from Walt Disney

The summary card does not define any translations. Depending on the age of the card it will show you some specific code page assignments. > After upgrading to Z/VM 5.4, We are seeing > Ascii x?5B? -> EBCDIC x?BA? > Ascii x?5D? -> EBCDIC x?BB? > What is the recommended telnet translation table we should be using? "Not applicable". Translation tables are not used for TN3270 since the emulator actually sends EBCDIC 3270 data streams. This is why you can configure your host code page in the emulator. It translates the ASCII characters you type into EBCDIC locally. So if you're seeing the wrong things when you XEDIT a file, it's because the host code page of the emulator when the data was entered via XEDIT is different than the one you're using. You can find the definition of each code page at http://www.ibm.com/software/globalization/cp/cp_cpgid.jsp. The xxxxyyyy translation tables included with z/VM are designed to translate between the codepage xxxx on VM and yyyy at the remote end, as represented at this website. > Was there a change in the default translation table between 5.2 and 5.4? No, but this isn't the problem in this case (assuming you created the file with XEDIT). > Could we have changed the default translation table and not leave tracks? Yes. All it takes is copying one of the translation tables over as STANDARD. It gets more interesting if you just copied TCPXLBIN and not the TCPXLATE source. The following applies to non-TN3270 apps (including linemode telnet): The "best" translation table z/VM provides is 09240923. This is ISO 8850-15, both ASCII and EBCDIC. But the best table and best table for you to use are two different things, depending entirely on the applications and how you have the data stored. It is vital to choose translation tables that reflect the data. If the data was entered at a 3270 terminal with a code page of 37 (US/Canada), then you want one of the 0037xxxx translation tables. xxxx depends on whether you transferring data to DOS, OS/2, Windows, or Unix. Western Windows uses 1252, Unix uses 819 (ISO 8859-1) or a euro-enabled variant such as 923 (ISO 8859-15), PC DOS is code page 437, OS/2 is code page 850. I have my emulator set to use code page 924 and I use Windows, so my best translation table is 09241252.
