``` Calculates any one parameter of the binomial     distribution given values for the others.                              Arguments     WHICH --> Integer indicating which of the next four argument               values is to be calculated from the others.               Legal range: 1..4               iwhich = 1 : Calculate P and Q from S,XN,PR and OMPR               iwhich = 2 : Calculate S from P,Q,XN,PR and OMPR               iwhich = 3 : Calculate XN from P,Q,S,PR and OMPR               iwhich = 4 : Calculate PR and OMPR from P,Q,S and XN     P <--> The cumulation from 0 to S of the binomial distribution.            (Probablility of S or fewer successes in XN trials each            with probability of success PR.)            Input range: [0,1].     Q <--> 1-P.            Input range: [0, 1].            P + Q = 1.0.     S <--> The number of successes observed.            Input range: [0, XN]            Search range: [0, XN]     XN  <--> The number of binomial trials.              Input range: (0, +infinity).              Search range: [1E-100, 1E100]     PR  <--> The probability of success in each binomial trial.              Input range: [0,1].              Search range: [0,1]     OMPR  <--> 1-PR              Input range: [0,1].              Search range: [0,1]              PR + OMPR = 1.0     STATUS <-- 0 if calculation completed correctly               -I if input parameter number I is out of range                1 if answer appears to be lower than lowest                  search bound                2 if answer appears to be higher than greatest                  search bound                3 if P + Q .ne. 1                4 if PR + OMPR .ne. 1     BOUND <-- Undefined if STATUS is 0               Bound exceeded by parameter number I if STATUS               is negative.               Lower search bound if STATUS is 1.               Upper search bound if STATUS is 2. ```
