Passing around multi-line strings - spinrad15069 - 07-23-2023
I'm trying to create a batch file which passes around a string with line feeds in it but its not working out. The continuation of the string is executed as a new command.
Is there anyway to encode a line feed or make this work?

You can create directly multiline strings with the caret (one empty line is required).
setlocal EnableDelayedExpansion
set multiLine=This is a ^
multiline text^
line3
echo !multiLine!
Or you can create first a newline character.
setlocal EnableDelayedExpansion
set LF=^
rem Two empty lines are required
set multiLine=This is a!LF!multiline text!LF!line3
echo !multiLine!
An explanation how this works can be found at [Explain how dos-batch newline variable hack works][2]

Expansion to [jeb answer][1] ,
Adding !LF!^ to each line would be easy
setlocal EnableDelayedExpansion
set LF=^
set multiLine=This is a!LF!^
multiline text!LF!^
line3
echo !multiLine!
