Correct. It first checks if the argument is just a single "+". If so, Vip opens the file from the following argument and jumps to its end $ vip + file # Go to the end of "file" Otherwise, if it is a number (told by 'format'), it opens the file and jumps to that number $ vip +42 file # Go to line 42 Else, the argument is taken as a "word" pattern to search for $ vip +foo file # Search for "foo" You can hit 'n' (find next) when the file is open. "Word" is a word according to PicoLisp delimiter rules, the same as if you start a search by hitting '*' on a word. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
