This guide is intended to for use with the PRAXIS v2.0 manual in the development of custom scripts which can be run within the PRAXIS measurement system. Praxis Scripts are Windows applications in themselves that run from within PRAXIS. They include visual forms on which you can place familiar user interface components like buttons, edit boxes, sliders, text editors, images, etc., and easily give them high level functionality by setting properties and writing code in DelphiScript (based on Borland Delphi) or VBScript (a language based on Microsoft Visual Basic).

The Scripts are developed using the Liberty Script Designer, which is an additional, separate application that is installed along with PRAXIS and which can be started from within Praxis. The Script Designer can be started by using the Scripts -> Design a Script menu on the Main Form.

Although Praxis was developed entirely using Borland’s Delphi language, and the components used are Delphi “VCL” components, other languages such as VBScript and JavaScript can be used to develop code if you wish. Most procedures and functions that are built into Delphi are also usable in a PRAXIS script, even when the script is programmed in languages other than DelphiScript. The Script Designer provides specific support, such as automatic generation of skeletal scripts, for the VBScript and DelphiScript languages.
