Hmmm, the ENIAC had no program store (at that time) and EDVAC was not
built till much later, 1952 according to my CCC.

EDSAC was built in Cambridge (England) and was operational in May 1949.
The IAS machine built in Princeton became operational in early 1952.
The EDSAC team developed a coding practice that strongly resembled
assembler code with relocation and linking. The "assembler" was built
into the machine as a kind of ROM, it was less than 100 instructions
long.
Just to keep the record straight.
