9.3 Determining how many characters a string has
This can be done with the string length command.
The syntax of a string length command is string length <string>.
The <string> is the string from which the characters must be retrieved.
This can be anything from a string as in variable to a command.
The string length command outputs a string that contains a number which
equals the amount of characters the string has.
If you were to input a list which contains an object that
is defined with braces, the braces will also be regarded as
characters in the string and not as items to designate a start
and top of an object. For example, string length "test
{foo bar} temp" would return 19 including the braces and
not 17.
