✦ Synopsis
This program enables the user to compute the elastic boundary conditions of straight ed$e dislocations using a procedure Program obtainable from: CPC Program Library, Queen's derived by Seeger eta!.

The result may be used to compute exactly the ionic (atomcomputer: UNIVAC 1108;Installation: HRZ, Universit~t ic)configuration within the dislocation core by using semi-Ffm discrete techniques.

Method of solution
Programming language used: FORTRAN V The final formula for the nonlinear anisotropic elastic field is obtained starting from Airy's stress function.
