Identifier

An identifier is a name given to a variable that the scripter can choose: It is the name that identifies the variable.

Rules

Binding rules for identifiers:

• Identifiers may consist of any ASCII characters (a-z, A-Z), numbers (0-9) and underscores (_)
• Identifiers must not start with a number (f.i. "9myVariable")
• Identifiers of local variables must start with an underscore

Examples of valid identifiers:

myVariable1
_localVariable95
_23Variable

Examples of invalid identifiers:

123Variable
9_vA#riable
_this&variable

Recommendations

It is recommended to write identifiers in camel-case-syntax. That means that all sub-words in the identifier are started with an upper-case character.

Examples:

myCamelCaseIdentifier
