numeric operands of arithmetic instructions may be of arbitrary (positive) length. The word mark approach allows the 1410 to access a field (depending on the instruction to be performed) at either end, so that the most efficient access can be chosen. This way, the compiler of a higher-level programming language has to take care of the initial increment of the operand address (by operand length minus 1) for example, for add, subtract, or multiply instructions.

1410 is a much faster system in the same spirit as 1401, but with significant differences, such as larger memory (up to 100,000 characters), more index registers (fifteen), and additional instructions. A remarkable feature in the pre-microprogramming era was a "compatibility mode" switch that allows
