How to Tabulate a History for Maximum Flexibility

On a human time scale, the input of fossil fuel carbon dioxide is not sudden. The rate is expected to increase for several hundred years and then to decrease again as reserves are exhausted, as shown in Table 5-1 (Broecker and Peng, 1982, p. 553). The program being developed here can be used to simulate the response of the ocean and atmosphere to a gradual input of carbon dioxide. 

In the following program, my table is called table(nent, nvar), in which the first column is the independent variable, time, which must increase monotonically down the table, and the other columns are one or more tabulated variables. In this example there is only one dependent variable, 

DIM sleq(nrow, ncol), unk(nrow), y(nrow), dely(nrow), yp(nrow) 

DIN plotz(nuroplot), plots(numplot), plotl (numplot), ploty(numplot)
