Character Substrings

Consider,

   CHARACTER(LEN=*), PARAMETER :: string = "abcdefgh"

substrings can be taken,

• string is `abcdefgh' (the whole string),
• string(1:1) is `a' (the first character),
• string(2:4) is `bcd' (2nd, 3rd and 4th characters),
• string(1) is an error (the substring must be specified from a position to a position, a single subscript is no good).
