In Unix (including OS X), run

  mred -z

to get MrEd with a MzScheme-like REPL using stdin, stdout, and stderr.

[That doesn't work in Windows, because the OS seems not to deliver a
 useful stdin, stdout, and stderr to GUI programs. If anyone knows how
 to solve this Windows problem, please let me know.]
