function Reply = zFixSurfaceData(Surfaces, Codes)
% zFixSurfaceData - Make lens surface data fixed.
%
% Usage : Reply = zFixSurfaceData(Surfaces, Codes)
%
% Surfaces is a vector of numbers of surfaces which should be fixed. Code is the surface parameter which should be made
% fixed. The codes are the same as for the zSetSolve function as follows :
%
%  ------------------------|------------------------------------------------|
%  zSetSolve Code         -|- Returned data format                          |
%  ------------------------|------------------------------------------------|
%  0, curvature           -|- solvetype, parameter1, parameter2             |
%  1, thickness           -|- solvetype, parameter1, parameter2, parameter3 |
%  2, glass               -|- solvetype, pickupsurf                         |
%  3, semi-diameter       -|- solvetype, pickupsurf                         |
%  4, conic               -|- solvetype, pickupsurf                         |
%  5-12, parameters 1-8   -|- solvetype, pickupsurf, offset, scalefactor    |
%  1001+, extra data values|- solvetype, pickupsurf, scalefactor            |
% -------------------------|------------------------------------------------|
% 
% e.g. zFixSurfaceData(1:4, 0:2) will set curvatures, thicknesses and glasses for surfaces 1 to 4 to fixed mode.
