Usually, you have vectored IO, so to save TYPE/EMIT/CR, you save something 
like OP-VECTOR (VFX, Gforth) and set it to another output vector (with your 
own TYPE/EMIT/CR).  You could have a word that defines a simple IO vector:

simple-io: ( type-xt emit-xt cr-xt "name" -- )

which just needs to be called to set OP-VECTOR.

One cell is easiest saved on the return stack.
