Yes and no.

There's a DOS function (Interrupt 21h/AX=6601h) that returns the current 
codepage number.  But you cannot change the codepage without editing 
CONFIG.SYS/AUTOEXEC.BAT and rebooting.

Also, note that on systems which don't install the codepage explicitly 
from CONFIG.SYS, DOS reports the default 437 codepage, although the truth 
is that the codepage burnt into the video BIOS is used.
