Hello Marco,
?In older releases of IBM's operating system each language
had its own memory methodology, and C was not available at that
time, my fuzzy grey cells indicate it came out around the early
70's, on PC's and Unix based IBM systems.

C - 1972 first release, 1978 for .
FORTRAN by IBM- 1958.
COBOL was designed in 1959 by
PL/1?? 1964 - IBM - first compiler released 1966
Assembler 1947 - by Kathleen and Andrew Booth? BUT there was an
earlier one of a similar type around 1944 for the first
programmable? British computer around 1944 and also one that was
more related to conventional Assembler for the British LEO I, where
the first program was written and tested in 1951. LEO II in 1954 and
finally the LEO III in 1961
For the LEO series the assembler was actually called Intercode.
The LEO III was still around and working around 1974 situated in ICT
T&SS, S&TS department
(later renamed ICL) in central London - I had to look up my
old CV for this one.? I do not recall working on it though but did
work on before that say around 1969 a ICT 1500 where I used Cobol
and did program in Cobol around 1965 on a IBM 1401 linked to a 7094
where Fortran and Assembler was also used.
Did use machine code on the 1401 around 1965/6 if only to create a
bootstrap program to get the system to boot up semi automatically
(but seem to recall it read the object deck from the card reader -
later converted to read a punch tape instead as faster).
.
That's as much as I remember - What do you want for a 77 year old
memory :)
