What I do:
cjk0:
$(MAKE) $(MFLAGS) RANGE=$(CJKBASIC) cjk
cjka:
$(MAKE) $(MFLAGS) RANGE=$(CJKEXTA) cjk
cjk: $(SLICE)
[ -z $(RANGE) ] && (echo must define RANGE ; exit 1) || true
$(SLICE) $(RANGE) $(R9).bdf > $(R9)_cjk.bdf
$(SLICE) $(RANGE) $(R10).bdf > $(R10)_cjk.bdf
$(SLICE) $(RANGE) $(R11).bdf > $(R11)_cjk.bdf
$(B2P) $(R9)_cjk.bdf > $(R9).pcf
$(B2P) $(R10)_cjk.bdf > $(R10).pcf
$(B2P) $(R11)_cjk.bdf > $(R11).pcf

You're always typing.
Well, let's see you ignore my
