Identifiers

HS variable names (identifiers) are case-sensitive strings consisting of one or more characters formatted as follows:

1. Must begin with an alphabetic character, "_", or "$".
2. Cannot be a HS keyword (e.g. a type declaration).
3. Can contain a colon that separates a namespace from a tag, ie: "namespace:tag"
4. Must not exceed 64 characters.

The following are valid identifiers:

• foobar
• xmlns:soap
• $recipe
• LIST
• _lotid
• _
• x500

The following cannot be used as identifiers:

• 0data
• list
• lot.id
• foo~bar
• a name
• if
• :tag:

An identifier can also be a string of any characters enclosed in single quotes. When enclosed in single quotes, identifiers can contain any ASCII characters. Names can be up to 64 characters long and are case-sensitive.

The following quoted strings are valid identifiers:

• 'lot id'
• '&Enter value'
• '@^@'
• 'list'
