PL/I was my introduction to structured programming (though it took a
somewhat loose approach to that). I always
Over my early years I spent time on a couple of implementations and
always had been amused by its somewhat COBOLish IO scheme
and spent a little time dabbling in variants such as the IBM PL/S,
UNIVAC PLUS, and the UofM interpretted PLUM.
Then I got introduced to C and it was all downhill from there :)
