  1. When I type l: 1 2, I get back list of 1,2. But when I type string: a b, why I get back `assign?

  2. What does ` sign does in Q? What is its significance?

The "assign" error means an "attempt to redefine a reserved word". See Runtime Errors. For the list of reserved words, see Reserved Words.

What does ` sign do in Q?

A back tick ` followed by a series of characters represents a symbol. For more details, see Symbols.

Note that q distinguishes between the back tick, ` and the single quote, '. When prints an error, it uses a single quote. For other uses, see Case.
