When creating Logic programs, there are limitations regarding the characters you can use. These are fixed by the language standard, and mean that for some parts of your programs, you can only use certain characters from the English character set.
The characters you can use vary depending on which part of a Logic program you are defining:
- Language Keywords—The keywords you use in Logic, for example, FUNCTION, are fixed by the language standard. They cannot be changed or translated in any way.
- Identifiers—We recommend that you use a restricted character set when you create identifiers in programs (see Restricted Character Set - Logic).
- String Constants—When you define constants, you can use any characters from any language. For example, you can use Chinese characters within the single quotation marks of the constant.
- Tag References—References to items in the database can use characters from any character set. However, the character set that can be used in the actual tag may be limited.
