len

Definition

Return the length of a string object.

This generic interface extends the intrinsic Fortran len function to support the fpx string type.

The returned value corresponds to the full length of the underlying character storage, including trailing blanks.

If the string is not allocated, the returned value is zero.

Examples

Basic usage:

type(string) :: s
 
s = 'foo'
print *, len(s)          ! 3
 
s = 'foo '
print *, len(s)          ! 4

Unallocated strings:

type(string) :: s
 
print *, len(s)          ! 0
