This guide is bundled with SlickEdit products to help you understand and become familiar with Slick-C, the language upon which the SlickEdit® programming editor is based. By learning Slick-C, you can modify the look and feel of the editor, write macros to perform custom operations, add new language support, and essentially extend the editor’s functionality until it is completely customized according to your preferences. Just another way SlickEdit lets you work the way you want. Getting Help Documentation This guide often refers to the SlickEdit® Help system for more information. In the SlickEdit application, the Help system can be accessed by selecting one of the Help submenu items. The contents of the SlickEdit Help system match the combined contents of the SlickEdit User Guide and this Slick-C Macro Programming Guide, both available as PDFs in the SlickEdit docs installation subdirectory. Documentation for all SlickEdit products is available for download from the documentation section of our Web site at www.slickedit.com/docs. TIP The best way to look up a Help keyword is to use the Index. In SlickEdit, from the main menu, select Help > Index. Index keywords are special terms that we have included to help you find specific information. To find all occurrences of a term in the Help, use the Help system’s Search tab (Help > Search). Use quotes around the term to find whole-word matches. Comments and suggestions about our documentation are appreciated. Please send feedback to [email protected]. Product Support For problem reports, please gather the following information and provide it to Product Support: • A description of the problem. • The language in which you are working (C/C++, Java, etc.) • Your SlickEdit program information including version and serial number. To get this information, click the SlickEdit menu item Help > About SlickEdit, then select the Program Information tab. Use the Copy to Clipboard button to copy the information so you can paste it into your problem report. • A code snippet to help us reproduce the problem (if possible). There are several ways to contact our Product Support team: • Use the SlickEdit® menu item Help > Contact Product Support. This will automatically gather your SlickEdit program information. • Send e-mail directly to [email protected].
