I think PL/M and XPL came from different worlds that did not
communicate. I think people saw XPL as too high level. I think PL/M
came from other system level languages such as PL/360 (?). My
recollection may not be right. I think it is amazing that at same
time those system implementation languages were considered great
advances, modern programming languages from BCPL to B to C was being
developed in obscurity. /Steve
