Getting CR into a variable

[foxidrive]

Does this get a CR into a variable?

The question was asked elsewhere and I had never examined the technique - I can't seem to echo a CR into a file.

Code: Select all

::Define CR variable containing a carriage return (0x0D)
for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a"

echo "%cr%">a.txt

echo a"%cr%b%cr%c%cr%d%cr%e%cr%f%cr%g%cr%"

you need to use delayed expansion.

Thanks Squashman, that's the tip!

Code: Select all

@echo off
setlocal enabledelayedexpansion
::Define CR variable containing a carriage return (0x0D)
for /f %%a in ('copy /Z "%~dpf0" nul') do set "CR=%%a"

echo "!cr!">a.txt

echo a"!cr!b!cr!c!cr!d!cr!e!cr!f!cr!g!cr!"

Additional the cause why %CR% doesn't work.

It's the parser phase just after the percent expansion of variables, it removes all CR's.
