FilmStar BASIC

With the addition of BASIC, FilmStar provides an environment for the rapid and cost-effective development of user-specific solutions. These range from automatic optimization, f-number analysis (as illustrated below), output of curved reflectors, tolerancing, quality control, etc.

An important example of the power of FilmStar BASIC is found in On the Reliability of Inverse Synthesis in Optical Coatings. If you're ready to advance beyond the limitations of point-and-click thin film software, you'll find there is no substitute for FilmStar.

BASIC IDE (Program Editor)

F-number Dialog Box

User Dialog Editor

IDE (Integrated Development Environment)

The screen shot at the left (click to enlarge) shows how the BASIC IDE appears within FilmStar. The IDE holds up to nine windows, making it easy to cut and paste code.

This particular program, fnum32.bas (included with FilmStar DESIGN), performs cone angle calculations by repeatedly averaging over series of angles. By NOT being 'hard-wired' into FilmStar DESIGN, users can modify the code to account for angular light distribution, etc.

The Enter values dialog was implemented with the visual User Dialog editor. In this editor users click on the desired Windows object (button, label, etc.) and drag it into place. Upon exiting the dialog, the code shown below is automatically pasted into the IDE.

  Begin Dialog UserDialog 372, 94, "Enter values"
      Text 27, 23, 73, 13, "&F Number"
      Text 20, 58, 81, 13, "&Resolution"
      TextBox 105, 20, 80, 18, .FnumText
      TextBox 105, 55, 80, 18, .ResText
      OKButton 250, 19, 88, 21
      CancelButton 250, 54, 88, 21
  End Dialog

Automatic Graph Creation

Integration with FilmStar Modules

FilmStar BASIC is integrated with other FilmStar modules: FSPlot Module, Workbook, Report Generator and FilmStar Database.

Here an FSPlot graph shows the results of cone angle calculations. The entire graph, including legends, is created automatically.

BASIC Language Help

FilmStar Extensions Help

On-Line Help

In addition to its well- documented set of language instructions, which will be familiar to anyone who has programmed in some version of BASIC, FilmStar BASIC adds special commands, keywords, and subroutines. These are documented in on-line help as well as in the BASIC object browser.

Macro of Macros

Data Entry Dialog

Running BASIC Programs

It is not necessary to run programs from the BASIC IDE. Once a program is developed it can be run as a macro assigned to keys <Shift+F1> to <Shift+F6>. As illustrated here, a Macro of Macros allows far more than the six programs assigned to shortcut keys.

The Optics Quality Control dialog illustrates compelling reasons to understand and implement FilmStar BASIC programs. Complex QC sequences can be reduced to step-by-step procedures, thereby reducing training costs and enabling coating facilities to sincerely comply with ISO-9001 requirements.

Ocean Optics Server

Bar-code Reader

Integration with External Programs

FilmStar BASIC lets users add calculation or data acquisition modules. As an example FilmStar includes an ActiveX server for data acquisition from Ocean Optics spectrometers. The server can run in stand-alone mode for testing or automatically from DESIGN and MEASURE.

FilmStar BASIC can also communicate with DLLs (dynamic linked libraries) developed in various Windows languages. Excel and other 32-bit Windows applications can utilize FilmStar's ActiveX interface.

As illustrated by Bar-code Reader, 16-bit software can be integrated with FilmStar via DDE (dynamic data exchange).
