Level 2 Help for POLYNOIS

 output data set

 this keyword determines the number of lines in the output picture

 this keyword determines the  number of samples in the output picture

 seeds=(s1,s2)          this keyword supplies the initial value
 of seeds s1,s2 for the Fortran function RAN. RAN(s1,s2) 
 returns a pseudorandom number and s1 and s2 are integer 
 variables or array elements that contain the seeds for computing
 the random number. The values  of s1 and s2 are updated during
 the computation to contain the updated seed. The default value
 is (0,0).

 NOISE=(I1,P1,I2,P2,I3,P3,....): the first constant I1 is the noise
 intensity level and the second constant P1 is an associated noise
 probability and so on.... A minimum of 1 pair and a maximum of 256 
 pairs of integers can be specified. The "In" values are restricted
 to values equal to or between 0 and 255. The "Pn" must be greater
 than 0.
