It's just PRIMOS, no E. And the '1' in place of 'i' thing was just a
Surprisingly few language extensions. Octal constants (:1234567). A
file inclusion facility ($INSERT FILE>PATH>XYZ.INS.FTN). Not much else.
Originally, much of PRIMOS was in FORTRAN, with some assembler (PMA).
Later, significant rewrites and extensions were done in PL/1 derived
systems languages (PLP and SPL), and even later some in Modula.
Awfulness is relative. Bill Poduska has said that writing most of the
system in a higher level language saved them a lot of time, over using
