Turbo Pascal was a game changer. Prior to this, I'd been learning to code with Computer Innovations C compiler. It required multiple compiler passes involving swapping floppy disks. What a pain. Turbo Pascal was small, compiled fast and produced tiny executables. It was a joy to use. Later, I used Delphi to develop the GUI for an electron microscope. It made GUI development so easy - even developing custom controls for knobs and 2-D sliders.
