Figure IV-1

 

This segment of a Mariner programmable sequencer flight program is given as an example of the sort of flexibility gained by adding a memory to the system. The first segment, the Executive, is only seven lines, yet it essentially controlled the software. The remaining code demonstrates a typical subroutine. The entire length of this program was 128 lines.
