@joe@f.duriansoftware.com I cringed at the C Compiler prices but eventually got a C interpreter that came with a Microsoft Press book on C in the early 90s. Not sure whether it was actually an interpreter or if it compiled but only wrote to ram and not disk (iirc the back cover flap included a coupon for a discount on Quick C that took it from too expensive for teenage me to slightly less too expensive for teenage me). No real advice on debugging so I crashed and burned on my first attempt to go beyond the lessons.
