Hi James,

Just to give you the results of your question:

cat /qsys.lib/mylib.lib/mysrcf.file/mysrc.mbr

works just fine, displaying the source member on the display.

Both

cat /qsys.lib/mylib.lib/myfile.file

and

cat /qsys.lib/mylib.lib/myfile.file/myfile.mbr

where myfile is a data physical file, get an "Operation not supported."
error when trying to open the file.
