Assignment conventions

There are rules for variable names. A variable starts with a letter or an underscore. It can't contain anything other than letters, underscores, or digits. It also can't be one of the following reserved words of Lua:

• and

• break

• do

• else

• elseif

• end

• false

• for

• function

• if

• in

• local

• nil

• not

• or

• repeat

• return

• then

• true

• until

• while

The following are valid variables:

• x

• X

• ABC

• _abc

• test_01

• myGroup

The following are invalid variables:

• function

• my-variable

• 123

Note

Lua is also a case-sensitive language. For example, else is a reserved word, but Else and ELSE are two different, valid names.
