Thank you, Jack. This worked perfectly. A slight modification so that the program will compress the current directory:

libname in "%sysget(PWD)";

proc datasets library=work kill nolist; quit;

proc copy in=in out=work mt=data; run;

options compress=yes; proc copy in=work out=in mt=data noclone; run;

If all our users run this on their SAS libraries, I think our disk usage will go from 91% full to around 60%.

My boss was trying to do something like this, but neither he nor I knew about the NOCLONE option. SAS-L is the greatest!

Yes, but you can do something similar with

----- proc datasets library=work kill nolist; run; quit;

proc copy in=sasuser out=work; run;

options compress=yes; proc copy in=work out=sasuser noclone; run; -----

We have deleted a lot of files, but there are a lot that we need to keep and would like to compress. I searched the SAS-L archives and found some macros that will compress all the datasets in a SAS library, but I was thinking: would it not make sense to be able to do this with PROC DATASETS?
