/// Non blank length of a string
///
/// Return the non-blank length of a character string. (That is,
/// the index of the last non-blank character when the string is
/// left-justified.)
///
/// # Brief I/O
///
/// ```text
///  VARIABLE  I/O  DESCRIPTION
///  --------  ---  --------------------------------------------------
///  STRING     I   Input character string.
///
///  The function returns the non-blank length of STRING.
/// ```
///
/// # Detailed Input
///
/// ```text
///  STRING   is the input character string.
/// ```
///
/// # Detailed Output
///
/// ```text
///  The function returns the non-blank length of STRING. This is the
///  same as the index of the last non-blank character in the left
///  justified string. If STRING is blank, NBLEN is zero.
/// ```
///
/// # Exceptions
///
/// ```text
///  Error free.
/// ```
///
/// # Particulars
///
/// ```text
///  Locate the first and last non-blank characters in the string.
///  Subtract to get the non-blank length.
/// ```
///
/// # Examples
///
/// ```text
///  The following examples illustrate the use of NBLEN.
///
///        NBLEN ( 'ABCDE' )             = 5
///        NBLEN ( 'AN EXAMPLE' )        = 10
///        NBLEN ( '   AN EXAMPLE  ' )   = 10
///        NBLEN ( '               ' )   = 0
