| BR has more than 97 built-in '''internal functions''' that return either [[numeric]] or [[string]] values. By using internal functions for tasks such as [[searching]] or [[summing an array]], both programmers and programs can be more efficient in getting their jobs done. Numeric functions may be used anywhere that a numeric expression is valid. Likewise, string functions may be used anywhere that a string expression is valid.

| This section presents these internal functions in alphabetical order. Their purpose is described, comments and examples are provided and related functions are mentioned.

| | |
| ===Syntax Conventions===
| |
| | |
| Numeric values are symbolized by the [[Variable|variables]] X and Y. String variables are symbolized by A$, B$, and C$. File reference numbers are symbolized by N, where N is the number associated with an opened file. Square brackets around a parameter indicate the parameter is optional. In all cases, the parameters or arguments which are passed remain unchanged.
| |
| | |
| Most Business Rules! internal functions are presented in syntax sentences rather than in syntax diagrams. Punctuation must be specified as indicated in these sentences. Numeric values are symbolized by X and Y whereas strings are symbolized by A$, B$ and C$.
| |
| | |
| File reference numbers are symbolized by N, where N is the number associated with an opened file.
