I/O and file handling
Files
Chapter 8 205
• An integer or real array (HP Fortran extension)
• Any of the above that is either a field of a structure or a component of a derived type
Note, however, that a section of a character array with a vector subscript cannot be used as an
internal file.
Accessing records in an internal file is analogous to accessing them in a formatted sequential
file; see “Formatted I/O” on page 209. For an example program that uses an internal file, see
“Internal file” on page 228.
