Apostrophes in Cell

How do I save a string to a cell that is in apostrophes?

ie. 'filename', not filename

Answer 1

[Jan]

If '''filename''' looks too confusing, e.g. when posting code in a forum:

quote = char(39);
abc = {[quote, 'filename', quote]}

Answer 2

[Matt Fig]

Use a double apostrophe everywhere you want one.

[Walter Roberson]

Right. So in order to use that string itself, you would use

abc = '''filename''';
