Patent US 4,099,230

A method and means for implementing the control structure of a computer comprising, for example the basic constructs of repetition, conditional execution, and nesting whereby, at any point, a machine language program can be decompiled into the English language source that produced it. The program is loaded into the memory of the machine in a manner to be location independent, so that each segment of a program may be debugged individually, if necessary, without affecting the balance of the program.
