     Yes. But this may be different in TC (I have no its RTL sources to
study and I lazy to disassemble it) and/or in different BC versions (and in
other compilers, of course).

     Because usually this was really non-important. Or, someone may decide
(but neither comment this in code nor document this), that permanent CY=1
before INT 0-25 is enough forever.

PS: BTW, int21() doesn't changes CY and, thus, depends from its external
state!
