Belated thanks to Penpen for his informative response to my previous effort. Please find below my revised code for reversing a string: @echo off & setLocal enableExtensions disableDelayedExpansion (call;) %= sets errorLevel to 0 =% (set lf=^ %= BLANK LINE REQUIRED =% ) set "cr=" & if not defined cr ...

Hi Dave, Thanks for the detailed explanation. I noticed consecutive LFs were being converted into a single space when I was trying to capture an input parameter inside the in (…) clause of a FOR /F loop using the REM tecchnique. I tried all kinds of crazy things, including piping the output from the...

Hi Dave and Jeb! :) How about this for strange behaviour? multiLine.cmd: @echo off & setLocal enableExtensions disableDelayedExpansion prompt @ for /f "delims=" %%A in (' for /f %%B in ("1"^) do rem # %1 # ') do @echo(%%A echo on @( @for /f "delims=" %%A in ("1") do rem: # %1 # ) | @findStr "^" @ech...

Hello Penpen and Happy 2018!

Your first solution is very reductionist… I love it!

My only criticism is that it prints 2 newlines for a single LF.

As for your second solution, I’m still trying to figure it out.

Thanks for your feedback.

Hello All, Sorry I’m late to the party, but here’s my proffered solution to this hoary old chestnut of a problem: @echo off & setLocal enableExtensions disableDelayedExpansion (call;) %= sets errorLevel to 0 =% set "testStr=uncopyrightable" call :splitStr testStr if errorLevel 1 ( >&2 echo(string is...

Hi All, I second Catalinnc’s sentiments! I’m not happy with this forum’s new style. I went through the list of styles provided by Steffen. They may look different on the surface, but they’re all the same underneath. By which I mean, they all use lists instead of tables. View the HTML source to see w...

Hi Steffen, Thanks for your reply. I tried your suggestions, but nothing worked. The new forum style overuses (imho) lists. The old style I was familiar with used tables, which are far easier for me to navigate. Please ask Peter the admin to add some styles and to allow mere mortals like myself to s...

Hello Again!

Is it just me or has the forum reverted to some default style? How do I reset it? I looked through my settings and I couldn’t find it.

TIA!

Hello Again! :) Wow, I can’t believe this topic is over 4 years old! :shock: What an enthusiastic little puppy I was in those days… :roll: Anyways, I’ve revised the code for my string strimmer. It is now completely expansion-insensitive and exploits the option to omit the closing quote in the last p...

Hi CirothUngol!

Are you aware of Judago’s str_math.bat script?

Hello All! I recently noticed some unexplained behaviour when appending a file to itself using type (from the command line): <nul set /p "=###" >hashes.tmp for /l %I in (1 1 8) do type hashes.tmp >>hashes.tmp So far, so good. The file size is 768 bytes, as expected. But when I do this: typ...

@Dave Thanks for the refresher! @Phil Something like: set "var=%var:#=$$%" could potentially double a variable in size. And if the variable is over 4095 characters to begin with, it will overflow and cause a fatal error. Is there any way to catch such errors and take remedial action? - SB

Hello All! I was trying to catch errors from overflowing variables (is it possible, btw?) when I noticed the following: @echo off & setlocal enableextensions disabledelayedexpansion :: create variable containing 4k hashes set "hashFile=%tmp%\hashFile.tmp" if not exist "%hashFile%&...

Hello All! In 2008, a Stack Overflow user asked how to echo a newline in Batch files. Someone called Ken posted this answer . This prompted a request for an explanation of how the code worked, but Ken was unforthcoming. So Jeb took up the slack and provided this now famous answer … two and a half ye...

Hi Phil,

I didn’t know you could coax a tab from robocopy like that. Thanks for the tip!
