3.10 Constraints

• Both set and global compiler variable names may not be empty, they must not contain white space, must start with a letter and must consist of alphanumeric characters. Cyrillic or Chinese letters are not alphanumeric characters. If CodeBlocks is given invalid character sequences as names, it might replace them without asking.
  
• Every variable requires its base to be defined. Everything else is optional, but the base is absolutely mandatory. If you don’t define a the base of a variable, it will not be saved (no matter what other fields you have defined).
  
• You may not define a custom member that has the same name as a built-in member. Currently, the custom member will overwrite the built-in member, but in general, the behaviour for this case is undefined.
  
• Variable and member values may contain arbitrary character sequences, subject to the following three constraints:
  
  • You may not define a variable by a value that references the same variable or any of its members
    
  • You may not define a member by a value that references the same member
    
  • You may not define a member or variable by a value that references the same variable or member through a cyclic dependency.
