-TWENEX COMPRESS/UNCOMPRESS
-(569 chars; more?) y
-Fighting to get my TWENEX files under quota, I noticed two undocumented
-executables, COMPRESS and UNCOMPRESS.
-COMPRESS <file> produces binary file <file>-Z that is smaller than the
-<file>. UNCOMPRESS <file>-Z prompts if it's OK to overwrite <file>, and if I
-say 'yes' produces a new version number of <file>. However, the contents of
-new <file> are not the original contents but some binary mish-mash.
-Anyone remember how to use these two programs, or another way to compress
-TWENEX files and then uncompress them back into their original state?

-EDIT  Command Format:
-@CREATE (FILE) /switches input.typ.gen
-or,
-@EDIT (FILE) /switches input.typ.gen (OUTPUT AS) output.typ.gen
-CREATE requires that input.typ.gen is a new file; EDIT
-works regardless of whether the file exists or not.
-/switches  is a list of settable switches which may
-be recognized.  If an illegal switch is encountered,
-the entire command is ignored.
-input.typ.gen, and output.typ.gen are TOPS-20 file
-specifications; recognition is available.  Output.typ.gen
-defaults to input.typ.-1 if it is not explicitly typed.
