When creating a compressed SAS data set from an empty hash object with the
OUTPUT method, the following error can occur:

  ERROR: An error has occurred during instance method OM_OUTPUT(505)
         of "DATASTEP.HASH".

This error occurs only if the overhead to compress the data would
increase the size of the data.  The following note is also issued:

  NOTE: Compression was disabled for data set WORK.MYHASH
        because compression overhead would increase the size
        of the data set.

For related information, please refer to SAS Notes  #005687 
and  #008632 .

This problem is corrected in SAS 9.2
