- The infix format is the standard FORTRAN mathematical expression format with the additional feature that you can use both ^ and for exponentiation. All statements must be terminated by a semicolon. In addition, the infix format allows BERNINA to read back the TEX that it generates, but do not expect it to understand TEX generated from anyone else, including you.
- The lisp format is the standard common LISP expression format, with the exception that the BERNINA function names are case-sensitive.
