Hi, the doc for 'fcast' is slightly confusing IMO with respect to the optional [steps-ahead] argument. Buried inside the help text there's the explanation: "Note that the steps-ahead argument should be given only in conjunction with the --rolling option." But in the top-line synopsis of the command this proviso is not hinted at, instead the argument looks like a regular option (which logically could well replace the startobs/endobs pair). I don't know if there is a man-page like syntax for the docs, because then it would also be wrong I guess, strictly speaking. So I propose to replace the line "[ startobs endobs ] [ steps-ahead ] [ varname ]" with "[ startobs endobs ] [ varname ] | [ steps-ahead ] <see --rolling below>" or something like that. thanks, sven
