 ## 2.2 Basic editing
 
-For the rest of this chapter we will use the CBL001.cobol sample program to demonstrate how rich of an experience editing COBOL in VSCode can be.  So, let's fire up VSCode, install IBM Z Open Editor (if it's not already) open up CBL001.cobol and get started.

 ### 2.2.1 Known file extensions
 
 For VSCode to use the capabilities of the IBM Z Open Editor, it needs to know that the file we are editing is in fact COBOL type.  VSCode accomplishes this by comparing the location and name of the file being opened against a list of known extensions to map the file to a known language.  For COBOL the following associations are used:
 
 - \*.COBOL\*
 
+- \*.CBL\*
+
 - \*.COB\*
 
 - \*.COBCOPY\*
