#### Outside Recipe Bodies
Parenthesized expressions can span multiple lines:
```just
abc := ('a' +
'b'
+ 'c')
abc2 := (
'a' +
'b' +
'c'
)
foo param=('foo'
+ 'bar'
):
echo {{param}}
bar: (foo
'Foo'
)
echo 'Bar!'
```
Lines ending with a backslash continue on to the next line as if the lines were joined by whitespace<sup>1.15.0</sup>:
```just
a := 'foo' + \
'bar'
foo param1 \
param2='foo' \
*varparam='': dep1 \
(dep2 'foo')
echo {{param1}} {{param2}} {{varparam}}
dep1: \
# this comment is not part of the recipe body
echo 'dep1'
dep2 \
param:
echo 'Dependency with parameter {{param}}'
```
Backslash line continuations can also be used in interpolations. The line following the backslash must start with the same indentation as the recipe body, although additional indentation is accepted.
```just
recipe:
echo '{{ \
"This interpolation " + \
"has a lot of text." \
}}'
echo 'back to recipe body'
```
