len(3I)

NAME
     LEN - Determines the length of a character string

SYNOPSIS
     LEN ([STRING=]string)

STANDARDS
     Fortran

DESCRIPTION
     The LEN intrinsic function takes Fortran character string arguments
     and returns an integer length.  This function accepts the following
     argument:

     string    Must be of type character.  It can be scalar or array
               valued.

     LEN is an inquiry function.  The name of this intrinsic can be passed
     as an argument.

RETURN VALUES
     The result type, type parameter, and shape are default integer scalar.
     The result has a value equal to the number of characters in string if
     it is a scalar or in an element of string if it is array valued.

EXAMPLES
     The following program returns the length of the character string I=37:

          PROGRAM LENTEST
          I=LEN('|...+....1....+....2....+....3....+..')
          PRINT *,I
          STOP
          END
