I/O statements
HP Fortran supports three types of I/O statements:
• Data transfer statements (see Table 8-4)
• File positioning statements (see Table 8-5)
• Auxiliary statements (see Table 8-6)
For detailed information about all I/O statements, refer to Chapter 10, “HP Fortran
statements,” on page 267.
NOTE Although the DECODE and ENCODE statements are available as compatibility
extensions for use with internal files, they are nonportable and are provided for
compatibility with older versions of Fortran. To keep your programs
standard-conforming and portable, you should use the READ and WRITE
statements with both external and internal files.
