Ahhhhh 'C', the first language I learned and still my favourite even though I have learnt quite a number since then. I also had a love affair with 8086 and 68000 assembler but sadly under windows, that is not a usable language these days.
One of these days I have promised myself that I will dive into ARM Risc assembler for the Raspberry Pi as I'm retired I do have the time! I love working that close to the CPU & registers.
The stuff one could do even with a relatively slow 8086 architecture CPU if one was prepared to do it the hard way with assembler, was astonishing!
