Hi Blessed day! I just want to know if there is any way of solving systems of partial differential equations in SAS. Reply would be very appreciated. Thanks very much!

In general, the answer is no. If you understand numerical analysis, you can use SAS/IML software to implement a simple 1D PDE solver. In the past I've implemented the standard 1D heat diffusion equation.
For higher dimensional problems you will find it easier to use specialized PDE software. For example, specialized software has tools for specifying the spatial domain, setting up finite-element meshes, and for solving large sparse linear systems at each time point.
