The commands manual gives the following CAUTION for OCTCOMP:

Before using this command be sure your logon group and account does not
contain files of the form Yn, Ynn or Ynnn where n is any alphanumeric
character. OCTCOMP may create temporary files named in this format and 
similarly named permanent files may cause an error condition

Could be another reason for not creating the output file.

Kindest Regards.
