This indeed makes END= work. Thanks for that advice.

The second part of my question was about this situaiton:

gunzip data/*gz can uncompress all 5386 files in less than one second.

My program can process them all as uncompressed in three seconds.

When I process them by reading compressed versions through a FIFO after
uncompression by "gunzip -c" it takes eighteen seconds.

Is this an inherent problem with using named pipes? I haven't run a
timing test using gfortran or nagfor.
