6.1 What is PURL?
The Programmable Universal Resource Language (PURL) is a command language used by some NDC Technol-
ogies products. The BenchMike Pro utilizes PURL to communicate with a host computer via the serial port.
You can write your own software programs with PURL to perform necessary functions, or you can utilize a NDC
Technologies program, such as LibraryPro. Note the symbols listed below. These symbols are used in this manu-
al to indicate non-printable characters.
