[Context: HL Kit … Basic Concepts and Terminology … Scripting Language … Language Basics]

The scripting language is line-based. Exactly one statement must be on a line, and each line is terminated by a carriage return (or newline). Long statements may not be split across multiple lines.

Any script line on which the very first non-whitespace character is a '~' is treated as a comment and ignored. Use of the '~' character anywhere else on a line (i.e. after the first non-whitespace character) is treated as normal scripting code. Therefore, it is not possible to specify "end-of-line" comments.

All script code is case-sensitive. Uppercase letters are distinct from lowercase characters in all circumstances. Therefore, the variable "foo" is distinct from the variables "Foo" and "FOO". This applies to all facets of the scripting language, which uses lowercase text exclusively for all keywords (e.g. "var", "if", "then", etc.).
