Understanding Name Rules for Variables in VEXcode VR

In VEXcode VR, you are required to give a name to a new variable when you create one.

The following article will cover:

• Valid Name Rules
• Possible Name Errors

Valid Name Rules

Variable names must be unique, but there are other specifications that the name must follow. 

Variable names are used in the following places:

1. Numeric (created using “Make variable”)
2. Boolean (created using “Make a boolean”)
3. List (created using “Make a List”)
4. 2D List (created using “Make a 2D List”)

Here is an overview of the criteria when choosing a valid name:

• The name cannot use special characters.

• The name has to begin with a letter. It cannot start with a number.

• The name cannot use spaces.

• The name cannot be a reserved word in VEXcode VR. A reserved word is a word or name that VEXcode VR is already using. Examples: for, while, break, else, not.

• The name has to be unique (only used once), but you can have different cases (one uppercase and one lowercase).

Possible Name Errors

When you create a variable name, if you see a “Name Taken” error, it means there is a duplicate name in any of the groups above.
