Thanks Ken. Sorry for a slow reply.
1) I added the use warnings;
2) I checked that the user (me) has read access to both files (At least, I right-clicked on their icon in Package Explorer of Eclipse, and saw that all three groups - Owner, Group, Other - had "Read" checked)
3) I do not know how to check the package namespace is correct in both files. I tried typing "package pmFile1;" into command line terminal but did not get a return value of 1. (I do not use terminal and command line much, I am sorry.) Could you tell me more specifically how I can check this?
Thanks again
