Allen, Cocke, and Jim Beatty led the development of the compilers for the machine. This represented a significant effort as the system was to be highly advanced and aggressively optimize code. Among its features was the ability to unwind loops, schedule instructions around the [[basic block]] concept, and separate those optimizations that were code-based vs. platform-based. The compiler would be used by both a [[PL/1]] front-end as well as an expanded version of [[Fortran IV]].{{sfn|Smotherman|Sussenguth|Robelen|2016|p=63}}
In a November 1967 project review, Herb Schorr outlined a delivery plan that would ship the first machine in 1971.{{sfn|Conway|2011|p=20}} The plan estimated that over 100,000 lines of Fortran and assembly code would be needed for the [[operating system]] and nearly 70,000 lines for the compilers, assembler, and library routines. He estimated the cost of development to be $15 million
