in my language, there are several ways of doing it:
var str=
"first line
second line
third line
";

var str=
"""first line
second line
third line
""";

var str=
<[[first line
second line
third line]]>;

where the 3rd form may be nested, but is otherwise about the same as the 
second form.

the main difference between the first form and the latter forms is that 
the first form still interprets \ escapes, whereas the latter forms 
don't use \ escapes.

note, it is also possible to use \ to avoid encoding newlines as well:
"first-word \
	second-word"
where the \ will eat the newline and any following whitespace.


another difference has to do with maximum string length allowed in the 
parser:
the first form is currently limited to around 4096 characters per string 
constant;
the latter forms handle strings of up to 1MB IIRC (it is either a 1MB 
max, or a 1MB initial/expandable buffer, I forget).

a lot depends.


at least off in C land, I was using large arrays of strings to represent 
"archives" for embedding collections of smaller resource files into C code.

technically, this was kind of "really annoying and sucked".


a little later on, this was replaced by embedding a WAD-based archive 
format (ExWAD) into the PE/COFF (Windows EXE/DLL) and ELF (Linux 
binary/shared-object) binaries. the WAD is historically related to the 
id Software WAD formats (primarily Quake/Half-Life WAD2), but is not 
exactly the same (different archive header, larger directory entries, 
hierarchical, supports Deflate, ...).

mostly this is used for embedding metadata, script-code, or resource 
data into program binaries (typically post-link). (for example: sticking 
reflection metadata into a DLL so the script VM can use it easier, 
stuffing the class-library into the relevant VM DLLs, ...).


functionally, though, this isn't too much different from embedding 
resource files into the JAR though for Java code.

the main "obvious" difference is mostly that programs like WinZip and 
similar wont be "clever" and assume that it is an archive, mostly 
because they have no understanding of ExWAD.


note that most normal (plain data) data resources have their own files 
or are stored in ZIP-based "pk" files though (for example: 
"resource/data001.pk" for game data), vs say, "resource/gamex86.dll" 
which may contain both Win32 / x86-specific native code, as well as a 
lot of scripting-language code and similar.


or such...
