Line wrapping

Any statement that is too long in Pine Script can be placed on more than one line. Syntactically, a statement must begin at the beginning of the line. If it wraps to the next line then the continuation of the statement must begin with one or several (different from multiple of 4) spaces. For example:

may be wrapped as:

A long plot call may be wrapped as:

Statements inside user functions can also be wrapped. However, since a local statement must syntactically begin with an indentation (4 spaces or 1 tab), when splitting it onto the following line, the continuation of the statement must start with more than one indentation (not equal to multiple of 4 spaces). For example:

Do not use comments with line wrapping. The following code does NOT compile:

The compiler fails with the error: Add to Chart operation failed, reason: line 3: syntax error at input 'end of line without line continuation'. To make this code compile, simply remove the // a comment comment.
