It's per process (unlike MSDOS, where it's global).

Presumably, either in the basepage or on the stack. In MiNT, it's stored
in the process structure. In either case, trying to manipulate it is
highly non-portable and virtually guaranteed to break on some future
version of TOS/MiNT, not to mention RTX or MX2.
