Do multiload '.import' statements run in parallel?

Hi

I have a single multiload step with several '.import' statements, each one using a specific lay out and applying certain DML's (running under MVS). When I run my multiload does it perform one pass of the input file and do all the ".IMPORT" in parallel? Or multiple passes of input file for each ".IMPORT" command?

Thanks
