Keywords

Reserved keywords

The names that follow are reserved by ViviFire. Thus you cannot usually use them for names of programming elements, for example, variables and procedures. But if you must use a reserved name, you can write it between a pair of backticks (`). See Keywords as Element Names for more information.

Note: We do not recommend that you use such escaped keywords, because they can make code less easy to read and to change.
