0x41 is a non-blank spacing character. 0x00-0x3F are reserved as 3270
control characters, in which only 0x05 (TAB) is displayable. If you do
not expand tabs in XEDIT, it will be converted to a Field Mark (0x1E,
overscore semicolon). All others in that range are converted to my
NONDISP character (0x79, ` in this case).
0xFF is defined as non-displayable in the 3270 architecture and so is
converted to NONDISP.

Re: XEDIT and non-printables
Depends on what you mean by carefully. Whenever you overtype any character on a line, the whole line is processed and many times unprintable characters get translated. I learned EDIT (before there was full screen) and I always resort to using c/stringin/stringout/ commands or ALTER bytein byteout commands when editing a file that has unprintables in it.

Re: XEDIT and non-printables
You can instruct CMS to translate non-printables: SET NONDISP is the default. With this setting: when XEDIT encounters a char in a position on a changed line, it keeps the non-printable if it was non-printable before, otherwise it becomes a . Hence: if you delete of insert characters that make the move, the non-printable is lost and replaced by a . (a 3270 can't tell XEDIT what happened in a field, XEDIT can only know which fields got changed) I also learned that this nice theory doesn't work if running with SET TEXT ON or SET APL ON, every non-printable becomes a if you touch the line. Therefore: - avoid touching lines with non-printables - set the NONDISP character to something else than , best a character you cannot type on the keyboard (and not a blank like you seem to have). 2008/5/20 Bob Bates [EMAIL PROTECTED]: Depends on what you mean by carefully.

Re: XEDIT and non-printables
I have seen this before. The x'11' seems to be special 'sometimes'. I just tried it with x3270 and did not have a problem. The last time I hit it was many years ago about the time I was using either extra or a real 3270 device so I think it is hardware or emulator related. (I really think it was back on real hardware.)

Re: XEDIT and non-printables
Xedit will never send X'11' to a 3270 when present in data, everything below X'40' is replaced by the non-disp character. 3270 control characters do exist below x'40': Start field, Set Buffer address, ..

Re: XEDIT and non-printables
Checking my 3270 Reference Summary after blowing the dust off I see - x'11' is 'Set Buffer Address' - the next two bytes are the address on the screen where following characters are displayed.

Re: XEDIT and non-printables
If you need to edit data with non-printables, ensure that you have IMAGE set to OFF - this will stop XEDIT from trying to treat occurrences of x'05' as TAB characters and x'16' as backspace characters. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Stephen Frazier Sent: Wednesday, 21 May 2008 5:16 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: XEDIT and non-printables Checking my 3270 Reference Summary after blowing the dust off I see - x'11' is 'Set Buffer Address' - the next two bytes are the address on the screen where following characters are displayed.
