I hope you're joking - talk about making code unreadable, comments that
look like code are (IMO) a very BAD idea. The indentation level makes it
perfectly clear what goes with what, and if it doesn't then change the
structure of the code.
IMO
IF XOOS.ALL.COURSES='Y' THEN
some lines of code
END ELSE ;* IF XOOS.ALL.COURSES='Y' THEN
some lines of code
END ;* IF XOOS.ALL.COURSES='Y' THEN
is much less clear than my preferred way of formatting the same
structure:
IF XOOS.ALL.COURSES = "Y"
THEN
some lines of code
END
ELSE
some lines of code
END
I can easily see the start and end of both the THEN block and the ELSE
block and also easily see to which condition they belong.
The same structure can be used for ALL conditional statements and each
block is always easy to find and associate with it's starting statement,
eg:
READU record FROM file,id
ON ERROR
statements
END
LOCKED
statements
END
THEN
statements
END
ELSE
statements
END

I'd argue that any END statement that's more than a handful (8-10) lines
from the opening IF (or whatever) statement should have a comment.
Here's an example (that's not long enough to satisfy my 'handful'
argument
above):
IF XOOS.ALL.COURSES='Y' THEN
some lines of code
END ELSE ;* IF XOOS.ALL.COURSES='Y' THEN
some lines of code
END ;* IF XOOS.ALL.COURSES='Y' THEN
