%======================================================================*
% FORM LETTERS E. Myers and F.E. Paige
%
% Macros to type form letters with a common text to a list of
% people. The syntax is:
%
% \formLetters{<letterhead-stuff>}{<text-file-name>}
% \BL Prof. John Doe
% Physics Dept
% U. of Nowhere
% Nowhere, Somewhere 12345679
% \V\Whoever{Prof.~Doe}
% \EL
% \BL Dr.\ William Barcode
% Department of Physics
% Ferbilab
% Batcave, IL 60510 USA
% \V\Whoever{Dr.\ Barcode}
% \EL
% \BL ...
% ... \EL
% ...
% \bye
%
% where <letterhead-stuff> is stuff to be executed before the address is
% printed and <text-file-name> is the name of a file containing the
% generic text of the letter following the standard TeXsis letter format,
% beginning with \body:
%
% \body
% Dear \Whoever,
% ...
% \closing
% Sincerely yours,
% Joe User
% \endletter
%
% The text file can use any other control sequences defined by
% \V\name{...} between \BL and \EL.
%
% Replace \formLetters with \formLabels (no arguments) to print out
% your mailing list in a tabular form suitable for printing on mailing
% labels. Or use \formEnvelopes to print directly on envelopes, if
% your printer can do so. Set \theSignature and \ReturnAddress if you
% also want a return name and address on the envelope.

\message{Form Letters.}
% \formLetters{<letterhead>}{<file>} sets things up to make a series of
% form letters. The commands in <letterhead> are executed before the
% address, to make a letterhead or print the sender's phone number.
% The file named by <file> contains the text of the letter, which is
% printed below the address. This text can use any ``variable'' control
% sequences defined by \V in the address list.
