Code after the line containing "//" (with the entire line being blank) can be distinguished from the preceding code.

Since the code after the // blank line does not need to be executed, it is sometimes difficult to see which parts are no longer needed when the JCL file is very long.
I hope to visually distinguish it from the preceding code, for example by adding a light background color or changing it to a comment color.

No file or test is named. Start by locating the VS Code extension's JCL syntax-highlighting or blank-line handling, then reproduce the behavior with a long JCL file containing a blank line whose line includes //; done means code after that line is visually distinct while preceding code remains unchanged.
