- While skimming the VMS System Routines manual for something else, I found
- a chapter entitled "Data Compression/Expansion (DCX) Routines." The
- introductory note states "There is no DCL-level interface to this facility nor
- is there a DCX utility."
-
- With a good bit of time and effort, I suppose I could learn how to use these
- routines to write my own compression/decompression programs. But since I have
- no prior experience, I'd like to pose a few questions first:
-
- 1) Is it correct to assume that since the DCX routines are part of VMS, they
- will be "better" (however that may be defined - faster, more reliable, etc.)
- than other available compression packages for processing files in our system (a
- VAX 6320 running VMS 5.4-3, soon to upgrade to 5.5)?
-
- 2) Does anyone else have experience exploiting these routines? Would you
- recommend them?
-
- 3) Are there any publically available packages based on DCX?
-
- 4) Assuming that the answer to 1) is yes and 3) is no - would the advantage of
- DCX be sufficient to warrant trying to master it? Or would it be best to just
- use something already available?
-
- Thank you for your help.
