string

Definition

Represents text as a sequence of ASCII code units. The derived type wraps an allocatable character array.

Examples

type(string) :: s
s = 'foo'

Remarks

The string implementation proposed here is kept at the bare minimum of what is required by the library. There are many other implementations that can be found.

Constructors

Initializes a new instance of the string class

string(character(:))

type(string) function string(character(:) chars) 

Parameters

[in]

chars

Examples

type(string) :: s
s = string('foo')
