The most important TRIPOS concepts have been the non-memory-management approach (meaning no checks are performed to stop programs from using unallocated memory) and message passing by means of passing pointers instead of copying message contents. Those two concepts together allowed for sending and

One notable feature of TRIPOS/BCPL was its cultural use of shared libraries, untypical at the time, resulting in small and therefore fast loading utilities. For example, many of the standard system utilities were well below 0.5 Kbytes in size, compared to a typical minimum of about 20 Kbytes for
