### Implicit vs Explicit Statements

In general, one worded, simple, or continuous phrases may be implicitly stated.

There are limitations for phrases containing certain char, including ` ` `-#$%`
|
||||
|
||||
These phrases fall under the explicit category in which quotation marks `" "` are necessary. These _can_ be escaped via the use of a backslash, but this should only really be used when there is one character that needs to be escaped.

Incorrect: `echo Hello World`

### Skipping lines
|
||||
|
||||
Phrases that are too long may become unreadable if they fill past the right edge of the 3DS bottom screen. Like typing with the **Enter** key for a keyboard, the inclusion of `\n` serves as a break to begin readouts with a new line.
|
||||
|
||||
**Example 5**
|
||||
|
||||
**Example 5**
|
||||
`echo "Hello \nWorld"`

> Hello
