Step 2. Using Variables > Naming Variables

Naming Variables

When it comes time to create your variables, there are some naming rules you must follow:

  • Variable names must start with a letter, an underscore character, or a Unicode currency symbol. Examples of valid variable names are FirstName, _department, or $userID.

  • After the starting character, variable names can contain any number of letters, underscores, numbers, or Unicode currency symbols.

  • Variable names must not contain spaces.

  • Simple variable names must not contain the dot (.) character. For example, setting a variable name to Sales.Manager will actually create a structure. (For more information on structures, see Step 10.)
