Consider this program:

Tyl identifies a value as string, only if it is enclosed in single quotation marks (').
First, we assign the string value 'Eitan', to the name string variable. As mentioned earlier, name variable gets its type upon assignment.

We can print a string directly:

If we want to print name: 'Eitan', we can't write ''Eitan'', because the internal quotations will not be interpreted as quotation marks for printing.

So we use the backward quotation mark (`):

The backward quotation mark (`) inside a quoted string, will cause the system to print a single quotation mark.

Strings can be added by the '+' operator:

Other options of adding variables and string literals:

Assigning a variable to a new variable:

In line 'yourcity mycity', yourcity variable gets the value of mycity variable, so their value is the same. Then, yourcity variable is assigned another value. Each time, the values of mycity and yourcity are printed.

String concatenation using the '+' operator:

In the second concatenation statement, we see that the last member of a concatenation sequence can be a statement in itself.
