Replace hex with hex

[hexadoodle]

I have an ascii file. I want to replace hex 01 through hex 1F and
hex 7F through hex FF with hex 20 (space).
I have searched and read and tried and not been successful.
Creating a macro for the find/replaces is totally acceptable.
I just did not want to do it one hex character at a time.
THANKS.

Use the pipe character for OR searches.
Try something like this untested example:

Search for: [\x01|\x02|\x03|.........|\xFF]
Replace with: \x20

----------------------------------
Use the following settings:
-----------------------------------------
[X] Regular expression
Replace All
-----------------------------------------
Configure | Preferences | Editor
[X] Use POSIX regular expression syntax
-----------------------------------------

That's not right. You don't want the square brackets; they turn the whole thing into a character class, which will match any one character that is \ or x or 0 or 1 or | or ... Just leave the square brackets out.

Alternatively, use a character class ( [...] ) and enter each required control character by holding down the Alt key while typing zero followed by the character's numeric value (in decimal) on the numeric keypad:

for hex 01 use Alt-01
for hex 1F use Alt-031
for hex 7F use Alt-0127
for hex FF use Alt-0255

Like this:
[<Alt-01>-<Alt-031><Alt-0127>-<Alt-0255>]
That contains exactly 2 hyphens, and <Alt-01> represents the single character hex 01, and so on, entered as explained above.

You can use a simple space character in the replacement, instead of \x20.

Aargh!
You are right (of course).

Thanks ben_josephs, I knew you would have the correct answer. 8)

I tried the alt sequence, both hold down alt and enter 001 etc
also hold down alt 0, then let alt go and 01 etc
with posix on and off and regular expression on and off
get error msgs cannot find literal expression or
invalid regular expression I would like to get this one correct,
it is simpler, however not easier for me

the \x01|\x02 ... works, however that's a lot of keystrokes and
about 5 people need
to create this macro and they had mistakes with instructions
on making a macro that replace hex 09 with hex 20

Thanks for your patience

This is standard Windows functionality.

Turn NumLock on.
Press and hold down the Alt key. Type 0, then 1. Let go the Alt key.
Etc.

[hexadoodle]

Tried it that way

I am entering the sequence [<alt-01> etc
that way in the Find what area after having the file
opened and selecting the Replace

[<?>-><>-<ÿ>]

[ben_josephs]

Those angle brackets shouldn't be there. I explained that in my earlier message.

I don't know how the question mark got into your expression. This is what it should be:
[--ÿ]
That doesn't look right on this page, but if you copy and paste it, it should be correct. (Make sure you remove a spurious trailing space that the web page may stick on the end.)

Thank you so very much
That works like a charm
I've been working on getting that
first cntl character...

Have a great weekend
