Funny, I don't think I ever saw that! We were told to not even bother learning BCPL, since Mesa was It.

I have found it,

"We rejected BCPL as, being too basic and too primitive, {For example it has no data structure except l6-bit integers. }, This left only SPL and MFL."

MPL eventually became Mesa.
