We probably didn't do a good job in explaining. It's used in 'include processors' where the included file may cause new files to be included, so you feed the '.im' line back to the 'fanintwo' stage, I am also fond of 'fanintwo' when I nibble on the input records. For example to generate all valid abbreviated forms (to feed into the 'loookup' reference).
PIPE (END \) literal COPYfile REName | split | i: fanintwo autostop | o: fanout | verify -1 /abcdefghijklmnopqrstuvwxyz/ | substr 1;-2 | elastic | i: \ o: | cons For your original problem, it seems to me that 'fanin' and 'buffer' are appropriate. Sir Rob the Plumber
