Network Definition Language

<p>NDL (Network Definition Language) was a compiler on <a href="/facts/Burroughs_Corporation/NAEwIvpU">Burroughs</a> <a href="/facts/Burroughs_Large_Systems/FwY7EqrB">Large</a> and <a href="/facts/Burroughs_Medium_Systems/9eRsahNt">Medium Systems</a> computers used to create a network definition file for a data communications controller (DCC) and object code for a data communications processor (DCP) that interfaced between a message control program (written in <a href="/facts/Burroughs_large_systems/FwY7EqrB">DCALGOL</a>) such as (<a href="/facts/RJE/x0usMfke">RJE</a>), (MCSII) or (<a href="/facts/CANDE/q7W0CHrS">CANDE</a>) and the computer's line adaptors and terminal network.
</p><p>Burroughs Network Definition Language allowed many parameters of the mainframe communications adapter, modems (where used), protocol and attached terminal to be defined. However it treated the low-level operation of the <a href="/facts/Polled_I%2fO/WVa88JIg">multi-drop protocol</a>, including the modulus of sequence numbers and the algorithm used for <a href="/facts/Cyclic_redundancy_check/u2exo4sv">CRCs</a> etc. as primitives.
