Simulink mask display programmatically, how to make line shift?

I use this command to set up mask display programmatically:

set_param( gcbh,'MaskDisplay', ['port_label(''input'', 1, ''in1''); port_label(''output'', 1, ''out1'');'] );

In the mask editor it afterwards appears in one line as:

port_label('input', 1, 'in1'); port_label('output', 1, 'out1');

which is a bit annoying when the block has many ports.

How can I make it appear in multiple lines, like:

port_label('input', 1, 'in1')

port_label('output', 1, 'out1')

use char(10),

set_param( gcbh,'MaskDisplay', ['port_label(''input'', 1, ''in1'');',char(10),'port_label(''output'', 1, ''out1'');'] );
