Well I have been programming in Cobol since around 1964/5 from IBM
1401,7094, ICL1900's,IBM360s and yes a lot more after the 60's and I do
not recall using anything other than DELETE having move the record key in.
Now I cannot say it was the same for the 1401/7094 as I do not have a
manual to hand but 360 and 1900 yes.
The idea of use high-values into the key I have never seen but there
again my memory may be playing tricks and I am only 72.
