Detailed Description

F77 compatible character class.

A minimal class used when passing string arguments from C++ to FORTRAN 77 (received as FORTRAN 77 FortranCharacterString strings), and subsequently returned back to C++ as properly zero terminated strings.

When the FortranCharacterString destructor is activated the zero-termination of the c-string is automatically managed. Zero termination is also done each time a string array is subscripted using

    FortranCharacterString::operator()(size_t index)
(1) F77 truncates strings when FortranCharacterString variable is short

(2) F77 pads variable with blanks when assigned string is short

(3) F77 represents a string as a pointer followed by a length

(4) A string array is stored in contiguous memory
