24: .I Movie
25: converts a script in a movie language
26: into an internal representation, then displays it in a window on a
27: Teletype 5620, AT&T630, or X11 system (depending on which version has been compiled).
28: If the filename is of the form
29: \f2file\f(CW.s\f1,
30: .I movie
31: creates the intermediate form in
32: \f2file\f(CW.i\f1,
33: which will be used in subsequent calls if it is more recent than
34: \f2file\f(CW.s\f1.
35: The options are:
36: .TP

113: each presented as a rectangular sub-window.
114: .BI view
