More about the tilde character or more specifically hex 'A1'
 
1) after the long discussion laast week we have to talk HEX and not dispaly
 
2) different emulators or different code pages might  show something
diffrent for  hex "A1" - I don't think it was even available on the real
hardware unless you got a special APL terminal. 
 
3) in any case - I am using HEX 'A1' as the default non display character
when I send data to the terminal (how it displays is dependent on your
terminal emulation and code page setting. No code page for VM/370 terminals
just HEX.
 
When I receive the data string back from the terminal I ignore the "A1" in
the string because that could be any one of 50 different characters that ae
non-displayable - No way to update those characters in the file except via
the HEX display.
 
So when you entered the "Tilde" I received HEX A1 and I could not update the
file/table becasue it could represent any non-displayable Character. I just
ignored it and the file/table remains unchanged. What you saw was not
necessarily blank but what was in the file before that.
You probably saw the TILDE when you entered it in your emulator but when you
hit enter it reverted to what was there -In the file/table before you hit
the enter.
 
When you do the update in the HEX DISPLAY I update the table from that
display.
 So you will see it in the edit screen as an undisplayable. Which happens to
be tilde/
 
Try updating a line with hex'A1A1A1020202'.
When you go back to the edit screen you wil see 6 Tilde Caharacters.
But the file will have the corect data and you can see that in the HEX
display.
 
Again the reason I chose the TILDE is because it is very rarely used(at
least by me) (and on the display if there are a lot of them it does not take
too much room in the byte and most emulators will display it. So screen is
not cluttered.
 
I can change that to something different - just need a well thought out
suggestion -but every character is going to have same problems.

Ok I can enter tilde with hex.

Not an often used character anyway.

The [] brackets are being displayed as tildes. (All other
"special" characters seem ok)
