While I have never been a professional programmer, I have done small amounts, both at work and home. I've learned over the years, FORTRAN, BASIC, Pascal, C, Python, REXX, Bash along with 8080, 6502, 6809, 8088 & Data General Nova/Eclipse assembler. Even worked in octal and hex on some systems, not to mention AMD AM2901 bit slice processor. Other than that, no experience at all. 😉
