This is true but... can I redirect output to every file I want using a
simple one-line syntax?
It could be interesting, as in the unix world everything is a file:
PRINT "Program started" TO "/var/log/messages" ' append? or...
PRINT "Program started" APPEND "/var/log/messages"
...or something like that. Truth is that one can make a subroutine to do it.
