    The PDELAN language [21] represents another approach to assist users in the solution of PDEs. It is an extension of Fortran containing a finite approximation mechanism. PDELAN programs are first translated by a preprocessor into Fortran programs that are then compiled by a Fortran compiler and executed. PDELAN enables the user to solve complex sets of parabolic PDEs. However, considerable knowledge of finite-difference algorithms is required, and the language itself seems very difficult to master. There are three basic declarations in PDELAN: MESH, VARIABLE, and OPERATOR, which correspond to the three basic elements used in finite-difference algorithms. In addition, there is a DOMESH statement that serves to specify the way finite-difference operators are to be applied throughout the mesh. The main advantage of PDELAN is that it produces efficient programs that compare very favorably with handwritten codes.
