You can move between documents by clicking on the tabs at the top of the Editor Workspace. The tab for the current document will always be highlighted. Line numbers are displayed along the left margin (this feature can be turned off in Editor Options).

The Editor Workspace supports syntax highlighting for the ScanExpert scripting language, as follows:

The Control Panel contains a status display area as well as 4 buttons.

Editor4

The Editor control panel

•	Syntax Check: Click on the Syntax Check button to automatically check for formatting and/or syntax errors in your script or study formula. Always run a syntax check before saving a script or formula.

If a syntax error is found, it will be displayed in the status display area below the buttons.

Editor5

Syntax errors are displayed in the control panel

Double click on the error and you will be taken to the line in the editor where the error was found.

•	Editor Options: Click on the Editor Options button to call up the Editor Options dialog where you can configure various editor settings, such as display/operational characteristics and keyboard shortcuts.

Editor6

The Editor options dialog

•	Color Picker: Click on the Color Picker button to call up the Color dialog where can select basic and custom colors for script functions that accept colors as input.

Editor7

The Editor color picker dialog

When you select a color using the Color dialog, the corresponding ColorToRGB() function call will be saved to the clipboard so that you can paste it into the current script, as needed.

Editor8

•

Compile: Click on the Compile button to compile a formula study into binary object code. Compiling a formula study is only necessary if you wish to distribute a particular study but do not wish to share the actual source code. After a formula study is compiled it is saved with a file extension of .DGX. The ScanExpert Viewer recognizes .DGX files as compiled studies and will load them at runtime, as needed.

Note: The "compile" option will only work with ScanExpert study formulas. You cannot compile a script. If a compiled version of a study exists along with a source-code version, the compiled version will always be loaded by the ScanExpert Viewer (the source code version will be ignored).

To compile a study formula:

•	Load the formula into the editor.

•	Click on the Syntax Check button to perform a syntax check on the formula.

•	Click on the Compile button and you will be prompted to confirm the action.

Editor9

Confirm the Compile operation

Click on the Continue button and the Save Compiled Version dialog will prompt you to supply a file name.

Editor10

Save the compiled study into the Studies folder
