G c de in- terpreting, system parameter m dif icati n, G c de editing, t l parameter setting, t l c mpen sati n, etc. were included in the system. Interpreting and implementati n f G c de is ne f the m st imp rtant parts. T he c mp siti n and characteristics f the G c de were analyzed. The G c de interpreting pr gram was devel ped independently. The interpreted pr gram was l aded int the buff er f G g l card t executing c rresp nding perati ns. The interpreting pr gram has realized rec gniti n f variables, expressi ns and macr pr - grams and has res lved the pr blem f c ntinu usly l ading f multiple pr grams. T he in- terpreting pr gram has been pr ved f easible thr ugh example verificati n.
