As soon as you enter text in the VLISP Console or text editor windows, VLISP attempts to determine if the entered word is a built-in AutoLISP function, a number, a string, or some other language element. VLISP assigns every type of element its own color. This helps you detect missing quotes or misspelled function names. The default color scheme is shown in the following table.

The VLISP text editor provides color coding for LISP files, DCL files, SQL files, and C++ language source files (see About LISP, FAS, and Other File Types [AutoLISP] for a list of file types recognized by VLISP). VLISP uses the file name extension to determine a file's type, and then selects the color coding accordingly. You can change the color coding style associated with a file type by clicking Tools Window Attributes Syntax Coloring from the VLISP menu bar. All text entered in the Console window is treated as AutoLISP code.
