Raincode Legacy Compilers are aimed at making the transition to the .NET platform as smooth and as painless as possible. Therefore, accurate mainframe emulation is an essential feature:
All numeric types – except for floating points – are bit-wise equivalent to their mainframe equivalents, including bit ordering in bit strings, endianness and sign representation
The behavior implemented by the Raincode Legacy Compilers is not derived from a standard or a text book. It is derived from the mainframe implementation and the exact same behavior is reproduced, even when it contradicts the original language standard or its own documentation.
