"My purpose there was to avoid the automatic "\n" appended by print, ..."

print does not do this. From its documentation:

"The current value of $\ (if any) is printed after the entire LIST has been printed."

$\ is the output record separator. From the "perlvar: Variables related to filehandles" documentation:

"The output record separator for the print operator. If defined, this value is printed after the last of print's arguments. Default is undef."

I can't see anywhere in the code you posted that you have explicited defined $\ (e.g. $\ = "\n").

Check your shebang line (not shown in any of your posted code) for a "-l" switch. This is probably the most likely cause of "the automatic "\n" appended by print". See "perlrun: Command Switches" for details of the "-l" switch.
