24     C !INPUT PARAMETERS:
25     C***********************************************************************
26     C field - array to be mapped to grid space [ib,levs] and added to qdiag
27     C indx - array of horizontal indeces of grid points to convert to
28     C tile space[numpts]
29     C chfr - fractional area covered by the tile [ib]
30     C ib - inner dimension of source array AND number of points in
31     C array a that need to be pasted
32     C numpts - total number of points which were stripped
33     C npeice - the current strip number to be filled
34     C check - logical to check for undefined values
35     C chardiag ... Character expression for diag to fill
36     C kLev ..... Integer flag for vertical levels:
37     C > 0 (any integer): WHICH single level to increment
38     C 0,-1 to increment "nLevs" levels in qdiag:
39 jmc 1.8 C 0 : fill-in in the same order as the input array
40 molod 1.1 C -1 : fill-in in reverse order.
41     C nLevs ...... indicates Number of levels of the input field array
42     C bi ...... X-direction tile number
43     C bj ...... Y-direction tile number
44     C myThid :: my thread Id number
45     C
46     c IMPORTANT NOTE:
47     c
48     c This routine will result in roundoff differences if called from
49     c within a parallel region.
