3ecd8885ac67 Import from CVS: tag r21-2-22
cvs

83 For example, write

86 The "call" to `interactive' is actually a declaration rather than a function;

91 The argument of `interactive' is usually a string containing a code letter

94 give a code letter, its prompt, a newline, and another code letter, etc.
3ecd8885ac67 Import from CVS: tag r21-2-22

95 Prompts are passed to format, and may use % escapes to print the
