Support for Non-Standard MPE/iX File Types
The following types of MPE/iX files can be transferred to a remote host
using FTP.
• Standard MPE files with fixed, variable or bytestream format.
• Files with either binary or ASCII data types.
In addition, the latest enhancements enable the transfer of the
following types of non-standard files between two HP3000 machines.
• Privileged files (files with PRIV file code)
• Circular files
• Message files
• RIO files
• CM KSAM files
• NM KSAM files
• HPSPOOL files
The type of the file is transparent to the user. The user need not specify
the file type being transferring.
Of these, SPOOL files are transferred as fixed ascii files. The above
non-standard file transfers are not possible between an MPE and an
non-MPE system. However, SPOOL files can be transferred as fixed
ascii files from an MPE to a non-MPE system.
The client (FTP) and server (FTPSRVR) must be compatible to take
advantage of this feature. The above file types can be transferred
between like FTP/iX systems without the need for buildparms on the
command line. Buildparms included on the command line are ignored if
the file is a non-standard file type. The use of buildparms is accepted
only for standard file types (file code of zero).
Non-standard file type transfers to incompatible FTP/iX versions result
in a data transfer failure message. You cannot append to non-standard
MPE/iX file types with the use of this new feature. Non-standard file
transfers to non-MPE/iX systems also result in a data transfer failure.
Non-compatibility of client and server file transfer requests result in
appropriate error messages.
