You cannot return string. return expects arithmetic expression as
status. I agree, that message is a bit weird ... what exact vesion do
you have?

What you try to do? Either output result using echo or print builtin:

	print $backup_log,$backup_lis

in this case you can do something like

	DIRS=$(prep_directories 20000330 WEEKLY)

or you can set parameter explicitly in function:

	DIRS=$backup_log,$backup_lis
