/// 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
