Abstract : COGO (COordinate GeOmetry) is an open-end programming system oriented to problems in civil engineering. The system consists of three basic divisions, COGO MONITOR, COGO BASIC and COGO PLUG. The monitor is always in memory, as is COGO BASIC. The monitor reads a card or accepts information from the typewriter. It examines the descriptive (command) portion of the record. Monitor then sends control to either a basic routine or a plug for calculation. COGO BASIC is a set of subroutines which perform frequentlyused functions like the storage of known points or the conversion of degrees to radians. COGO PLUG is a set of subroutines each of which is called a plug deck. Each plug deck is used to solve more specialized problems like the area of a polygon or the intersection of two lines. Only one PLUG may be in memory at a time. Simple problems in surveying, structures, and mechanics are presented and solved in this report to show the use of COGO-1. The method for modifying COGO-1 and a modification program are included.
