% To assist in avoiding name clashes, the names of all symbols %
% defined here begin with "ldiag". However, this is not feasible %
% with user-defined labels and some labels used by users. %
% %
% <point> is two numbers, a point. %
% <length> is one number, a length %
% <angle> is one number, an angle in degrees %
% <dashlength> is one number, the preferred length of a dash %

% Tag dictionary operators
%
% Diag's tag dictionaries are kept on the same stack as other dictionaries,
% since there is nowhere else to put them. However, they are managed like
% a separate stack using the following operators:
%
% <tag> ldiagpushtagdict - Push a new, empty tag dictionary
% ldiagtoptagdict dict Find the top tag dictionary
% ldiagpoptagdict - Pop and destroy the top tag dictionary
% ldiagpopuptagdict - Pop top tag dict and promote its entries
% <array> ldiagpopsometagdict - Like popuptagdict but only those promote
% those labels listed in <array>
% ldiagdebugtagdict - Debug print of dictionary stack
%
% They are distinguished from other dictionaries by containing /ldiagtagdict,
% whose value is the <tag> which is used by ldiagpopuptagdict,
% and they are hopefully never the target of any non-tag definition because
% they are never the top dictionary, since push places the new dict second.
