Comment BASIC (Score 1) 633
My first language was BASIC. Initially on the Texas Instruments TI 99/4A, then on the Commodore 128D. I was 6-8 years old at the time
The first languages I was taught were Pascal and FORTRAN. My first real programming job was in Delphi, and from there (after a very short dip into SmallTalk) I moved onto C++ (with a small bit of Ada thrown in) where I stayed for many years before adding C# into the mix. Somewhere along the way I also learned Java, but never really got into it.
Since then I've written programs in most mainstream languages, everything from Perl and Python to Java, Javascript and F#.
The language I remember most fondly is Delphi. Easy and simple on the surface, especially the really easy way to build Windows apps, but with all the power of C++ if you dig deep enough, powerful enough that I got to know and more importantly understand, pointers in Delphi. It's no surprise to me that C# (having the same designer) borrowed so many excellent features from it. I've always considered myself really fortunate that it was Delphi and not Visual Basic that introduced me to Windows programming.
