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

Binding rules for identifiers:
- Identifiers may consist of any ASCII text characters (a-z, A-Z), numbers (0-9) and underscores (_)
- Identifiers must not start with a number (e.g "9myVariable" is invaild)
- Identifiers of user-defined local variables must start with an underscore
- Identifiers are case-insensitive.
- Identifiers cannot be the same as reserved words (e.g commands and functions).
Recommendations
It is recommended to write private variable identifiers in camel case syntax. This makes identifiers more readable:
private _myVariableName = 5;
It is also recommended to prefix public variable identifiers with your tag in order to avoid any potential conflict between addons, scripts and missions:
// Tag_identifier
UNIQUETAG_player = player;
A less encountered naming format is separating all sub-words with underscores:
_my_variable_name = 5;
