MPE/iX NOTES
The current MPE/iX
implementation of dd converts non-byte stream files to byte steam files
before processing them. File characteristics like file code, record size, and so forth are not pre-
served by this conversion. The output of dd is written as a byte stream file.
In addition, direct device input/output is not currently implemented.
For more information on how the current
MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
