Reformat Script - Protect some code?

[#1]

Reformat Script in JSL Editor is very helpful to get the code with a formatted structure.

Often it helps to find bugs in the code and to keep the overview.

But sometimes, it's the opposite.
Is there a way to protect code in a specific area from being shuffled by Reformat Script?

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
dt << Recode Column(
	dt:name,
	{Map Value(
		_rcOrig,
		{"ALFRED", "A",
		 "ALICE", "A",
		 "AMY", "A",
		 "BARBARA", "A",
		 "CAROL", "A",
		 "CHRIS", "A",
		 "CLAY", "A",
		 "DANNY", "A",
		 "DAVID", "A",
		 "EDWARD", "A",
		 "ELIZABETH", "B",
		 "FREDERICK", "B",
		 "HENRY", "B",
		 "JACLYN", //missing
		 "JAMES", "B",
		 "JANE", "B",
		 "JEFFREY","B",
		 "JOE","B",
		 "JOHN", "B",
		 "JUDY", "B",
		 "KATIE", "B"
		 },
		Unmatched( _rcNow )
	)},
	Update Properties( 1 ),
	Target Column( :name )
);

Select only part of your code and then reformat the script

[#3]

You mean: don't select some code around the protection area such that the remaining code gets consistent, then trigger Reformat Script?
Unfortunately, doesn't seem to work

[#4]

Jarmo's suggestion works well, however one has to reformat syntactically valid JSL

results in reformatting only the selected parts of the code

[#5]

Hm, syntactically valid JSL code - reformat works if I delete the code in the (non-selected) protection area.
So, the remainder seems to be OK.

I think the actual problem is:

The two pieces of code - above and below the protection area have to be - separately -  syntactically valid JSL code.

i.e. the protection area has to be on highest level - e.g. a whole function.

Good catch.

There is a work around.  The 

     Advanced=>Comment Block

does not change the structure of the code, it simply comments out a highlighted section of code.  If you Comment Block, then Reformat the JSL and then highlight and 

     Advanced=?Uncomment Block

you will achieve your goal
