VLISP recognizes the various types of characters and words that make up an AutoLISP program file and highlights the characters in different colors. This makes it easier for you to spot something incorrect quickly. For example, if you miss a closing quotation mark following a text string, everything you type continues to display in magenta, the color denoting strings. When you enter the closing quotation mark, VLISP correctly colors the text following the string, according to the language element it represents.
As you enter text, VLISP also formats it by adding spacing and indentation. To get VLISP to format code you copy into its text editor from another file, choose Tools Format Code in Editor from the VLISP menu.
