String literals written on multiple lines should not be used, especially since the new line characters are not part of the string
anyway. The concatenation operator || should be used instead. Moreover, if trailing comments are present, they can be automatically
removed by text editors and lead to unexpected results.
Noncompliant code example
foo: proc options(main);
put list ('Hello, /* Noncompliant; trailing space is not readable and may be stripped */
world');
end;
Compliant solution
foo: proc options(main);
put list ('Hello, ' ||
'world');
end;
