To my understanding TOS 1.4 works similarly to MS-DOS in this regard.
There is a limit on the number of resources that can be "open" simultaneously,
but those resources do get correctly freed when the resource is "closed".
(This was the big problem in TOS 1.0 and 1.2).

Under MS-DOS you can control these limits with lines in the config.sys file.
Under TOS (since it doesn't have a config.sys file) you have auto folder
programs like cachexxx.prg (which I think is comparable to the config.sys
line BUFFERS=) and foldrxxx.prg (which under 1.4 has an effect comparable
to the config.sys line FILES=).
