     COPY output-file-spec

     Makes a copy of the system dump file currently being examined.
     Each time the system crashes, new dump information is written
     over the contents of SYSDUMP.DMP.  The COPY command allows you
     to preserve the contents of the dump file by copying it to
     another file.  The contents of the SYSDUMP.DMP file are not affected
     by execution of the COPY command.

     If the paging file was used as a dump file instead of SYSDUMP.DMP,
     then the pages of that file that contain the dump information are
     not available for paging until they are explicitly released. The COPY
     command releases the dump pages in the paging file so that they are
     available for system paging.  Note that once the COPY command has
     released the dump pages for paging use, the dump information in these
     pages may be lost.  Subsequent dump analysis should be carried out
     on the copy of the dump file that was specified in the COPY command.
