Names

A name is an identifier used to represent an entity. The named entity can be any one of

A Robot (defined by a new control statement)
A Robot Type (defined by a NewRobotType definition)
A Defined Instruction (defined by a DefineNewInstruction definition)
A World Entity (defined by a WorldEntity command)
An Integer (defined by a DefineInteger definition)

It is permissable to have two different entities have the same name. That is, a robot and a world entity could all have the name, e.g. bob.

Names may be up to 31 characters long, and consist of letters (A-Z and a-z), digits (0-9), and the underscore (_) character. Names must, however, begin with a letter. Names are case-sensitive (uppercase and lowercase are distinct, so that abcd, ABCD, AbCd, and aBcD are all different names,

A name may not be the same as a RoBOTL keyword. RoBOTL keywords include:
