What Was Your First Programming Language?

[Jim Horn]

First used on a computer: IITRAN (Illinois Institute of Technology's own Univac 1108 language), then FORTRAN. (1971)
First used on my own: HP-25 (1975), HP-67 (1976), 6502 assembly and Tiny BASIC (KIM 1, expanded with S-100 bus, etc.; 1977)
First used at work: Rocky Mountain BASIC (HP 9835, 1979), then UCSD Pascal, C, 68000 and 8096 assembly
Honorable mention: FORTH (Voyager World Flight Engine Monitor System, 1985), C++, various HDLs (ABEL, AHDL, Verilog, VHDL, etc.), Mathematica 10.

Given the choice, I lean towards RPN, C++ and Verilog. Lots of fun!
