No. It (and the companion Expand Stage) are all about data sets. Now, that doesn't mean you can't "compress" a sequential file, you'd just have to do it with a singleton call to your O/S after creating it.

You need to execute in sequential mode to compress into a single archive. But you can certainly have a Sequential File stage downstream of a Compress stage.

I wouldn't use the compress stage for this. Just use a sequential output stage and add the command "gzip -i" to it . I'm not at a DataStage computer now, but when I do I'll send the exact syntax I use.
In the sequential file stage, just enter "bzip2 -c" to compress using bzip2, other commands have slightly differing sysntax to take their input from stdind.
