Add comments to CBL0006 and CBL0007

Since the Chapter 11.2.3 Conditional names isn't covered in the Labs, i changed the program in a way that the logic is different, but the task and results are the same. I also left the extra dot in the code, so you still have to search the error and correct it.

@klausmelcher Thanks for adding this! Do you think the comments can be added in the *.md file?
@MikeBauerCA What do you think?

I don't know how to obtain the same Syntax highlighting colors as used in the images of the *.md file

You can install COBOL Bitlang in your VSCode extension

@jellypuno I made an update to my pull request. Using COBOL Bitlang, I did not succeed in matching the colors exactly (commit 6ab9ba6). But with the HILITE AUTO command from Z/OS ISPF Editor, I got better results (commit 31f83ef).
If it is good enough, I can add further figures in my next pull request.

@klausmelcher I see you have added an image in this PR but do not reference it in the course. Where would you like to add the image?

@MikeBauerCA The reference is in line 2895 of the COBOL Programming Course #1 - Getting Started.md file. I would like to replace the image which is already referenced with a new one with comments, as suggested by @jellypuno.

LGTM, thanks!
