GWALL - Gravity and Cantilever Wall Analysis Program

GWALL Version 3 has been designed to provide a high degree of compatibility with its predecessor, version 2.42:-
    Version 2 data files can be read and processed by Version 3.
    The definition and usage of almost all engineering parameters is preserved in version 3.
    The methods of calculation are identical (apart from the implementation of finite surcharges).
    The formatting of printed data and results is preserved virtually unchanged.

To summarise, you should be able to read and process your version 2 data files and obtain virtually identical output using GWALL version 3.
