Eh, BASIC…
My first computer language was IBM 360 assembly:
a family friend had taken a course on the IBM360 and gave me all the material - he was really not interested in this stuff at all.
As a nerdy 12 or 13 y.o., I went through it front to back and also did all the exercises - of course, without any chance of seeing them run on a real machine!
I remember it being top quality for clarity and depth, I learnt about boolean logic, hexadecimal, truth tables, Karnaugh maps, the structure of a computer/mainframe and its peripherals, etc. etc.
My second language was 6502 machine code (i.e. manual translation from assembly) for a self designed and built computer, similar to the Kim1.
By that time, I was in high school, and they finally bought an Apple ][ - that was my first exposure to BASIC*.
I frankly found it limiting and ugly, but handy to throw together a quick thing.
Then FORTH, Pascal, Fortran, C, C++, Python, and now I’m getting a bit rusty…
*I was always skipping the religion class to go there, that earned me an “insufficient” mark at the end of the year, but it did not count for promotion, and I also forced the school to correct it, as it was not one of the allowed mark values (“scarce” was, I was just being obnoxious, as teenagers often do…).
