Below are the rules used for Visual Basic when naming procedures, constants, variables, and arguments:
1. Names cannot be more than 255 characters.
2. The first character must be a letter.
3. Spaces are not allowed.
4. The variable name cannot be a reserved word within Visual Basic.
5. Some special characters such as @, &, $, and # cannot be used.
Below are the variable naming rules for Java:
1. There is no restriction on character quantity.
2. The first character can be a letter of the alphabet, an underscore or, a dollar sign.
3. After the first character, the variable names can contain letters and single digit numbers.
4. Uppercase characters are distinct from lowercase characters.
5. Variable names are case-sensitive and using all uppercase letters are primarily used to identify constant variables.
6. The variable name cannot be a reserved word within Java.
7. No spaces or special characters are allowed. Below are the variable naming rules for Python:
1. Must begin with a letter or underscore.
2. Other characters can be letters, numbers or underscore.
3. Case Sensitive
4. There is no restriction on character quantity.
5. The variable name cannot be a reserved word within Python.

In Java, variables are called identifiers and out of these three Visual Basic is the only one that has a set character limit for its variable names. Visual Basic specifies that it cannot be any longer than 255 characters. For the most part, a majority of the variable rules are similar. They all specify that a variable name cannot be one of the reserved names and the first character must be a letter. Python is the language used by
