Well, getting 45m records from a 90m record data set by random access is a very poor design (not blaming you for the design, until you admit to it).
How many hits on the 70k-record file? Consider loading the data you need into a COBOL table, and access from there.
You'd have to explain how the 10m file causes effects to the 90m file, and the relationship of the keys between the two.
