LIMITS
This implementation of compress is limited to a maximum of 16 bit compression.
PORTABILITY
A binary-compatible version of compress, with more options including the ability to com-
press in place, is often found on
UNIX systems.
The –D option is an extension to traditional implementations of compress.
MPE/iX NOTES
The current
MPE/iX implementation of compress converts non-byte files to byte stream files
before compressing them. File characteristics like file code, record size, and so forth are not
preserved by this conversion. When you decompress the compressed file, it is written as a
byte stream file.
For more information on how the current
MPE/iX implementation may affect the operation of
this utility, see Appendix A, MPE/iX Implementation Considerations.
