C*********************************************************************** |
| 27 |
C field :: array to be mapped to grid space [ib,levs] and added to qdiag |
| 28 |
C indx :: array of horizontal indices of grid points to convert to |
| 29 |
C tile space[numpts] |
| 30 |
C chfr :: fractional area covered by the tile [ib] |
| 31 |
C ib :: inner dimension of source array and number of points in |
| 32 |
C array a that need to be pasted |
| 33 |
C numpts :: total number of points which were stripped |
| 34 |
C npeice :: the current strip number to be filled |
| 35 |
C check :: logical to check for undefined values |
| 36 |
C chardiag :: Character expression for diag to fill |
| 37 |
C kLev :: Integer flag for vertical levels: |
| 38 |
C > 0 (any integer): which single level to increment |
| 39 |
C 0,-1 to increment "nLevs" levels in qdiag: |
| 40 |
C 0 : fill-in in the same order as the input array |
| 41 |
C -1 : fill-in in reverse order. |
| 42 |
C nLevs :: indicates Number of levels of the input field array |
| 43 |
C bi :: X-direction tile number |
| 44 |
C bj :: Y-direction tile number |
