I cannot really help you with advice for the exact thing you are asking
for: side by side hex and ASCII.
That being said, you should note that ASCII is not really used for a long
time - as in decade or more. These days, characters/text are encoded mostly
in UTF-8 with variable character code length. So, looking at a file with
ASCII viewer/editor may not be that useful.
<Chuckle> I have prior knowledge that the character data is ASCII. There
are about a half dozen single byte codes evidently used for a as yet
undetermined purpose.
I would be extremely careful editing strings with a hex editor - it may
look like you are editing ASCII but you could easily corrupt the
underlining UTF code sequence. Then bad things might happen, such as buffer
overflow, etc, etc.

That's why no mention of "edit". "Display" was explicitly used.
Thanks
Hope it helps,
Tomas

I'm running Debian 9.8 with MATE desktop.
I'm exploring a data file with the intention of eventually parsing it in
a useful fashion.
Just downloaded ghex. I like the display format.
Its tools are inconvenient.
I need to:
1. Simultaneously display in _both_ HEX and ASCII format
2. Know the current offset in *DECIMAL* format.
{knowing the offset also in HEX might be nice}
3. Goto to an offset - expressed in DECIMAL.
4. Advance a specific number of bytes.
5. Search for an ASCII string.
6. Search for arbitrary sequence of bytes expressed as HEX.
Suggested tool(s) in Debian repository?
TIA
