Order/order code

I actually have the impression that the 'order/order code' terminology was more common in the UK; at Cambridge (see The EDSAC Order Code, and descendants such as the LEO); and at Manchester (see From Cathode Ray Tube to Ferranti Mark I). In the US, Whirlwind mostly used 'instruction' and 'operation code'. Jnc (talk) 13:11, 4 November 2025 (UTC)

I had a look through some PDP-1 documentation, but didn't see 'order' being used. Where should I look? Jnc (talk) 19:10, 5 November 2025 (UTC)
