Yes, the wording is a bit unfortunate. > The trf request works well, but it does some processing of its > input. The cf request is supposed to do the same as trf except it > would not process its input in any way. Unfortunately cf does not > seem to do a thing. It does: file foo: ***A*** ***B*** file foo.tr: ***1*** .di bar ***2*** .cf foo ***3*** .br .di ***4*** .bar ***5*** now troff -Tascii foo.tr gives: ... t***1*** n40 0 V160 H0 t***4*** n40 0 V200 H0 ***A*** ***B*** x font 1 R f1 s10 V240 H0 t***2*** wh24 t***3*** n40 0 V320 H0 t***5*** ... Perhaps it's helpful to think that, within a diversion, each line of a file inserted with .cf is handled as if it was preceded with `\!\\!'. I'll add this to the documentation. Werner
