 Arrays 



All arrays except COB, COC, XI and ETA are reused throughout the 

 program. The user is cautioned to consult each major program divi- 

 sion for assessment of array contents. 



X,Y,Z Dimensioned NUMXI x NUMETA. 



X2,Y2 

 X2P,Y2P 

 ATXA,ATYA 

 ATXB,ATYB Dimensioned the larger of N4, NS, ND, or IQUAD. 



A, B, C 



lie Dimensioned IRG (the number of Sp(S*) expansion 

 regions) . 



SX Dimensioned NUMXI-2. 



SY Dimensioned NUMETA. 



COB Dimensioned NMAX. Contains the conformal mapping 



transformation coefficients, B . 



n 



COC Dimensioned ^JMAX. Contains the conformal mapping 



transformation coefficients, C . 



n 



XI Dimensioned NUMXI. Contains the values of C for 

 determining the computing grid data. 



ETA Dimensioned NUMETA. Contains the values of n for 

 determining the computing grid data. 



Constants 



NMAX Number of conformal mapping transformation coefficients, 



B or C . 

 n n 



NUMXI Number of computing grid ? lines. With respect to the 

 computing grid in Program SSURGE, there is an extra E, 

 line at each lateral end. This requirement results from 

 the averaging procedure used in determining the grid 

 data. 



NUMETA Number of computing grid n lines. This is the same 

 number as in Program SSURGE.
