I've been using awk to process hourly weather data, storing 10 arrays with as much as 8784 data elements. If an array is incomplete, i.e., stops at 8250, etc., after the "END" command I fill the remaining array elements with the last available value for the array. However, when I then print out the complete arrays, I get 0's for the filled values instead. What's causing this?? Does awk have a limit in the array size that's preventing it from filling the arrays? Following is a snippet of the awk program. In the two print statements, the first time the array elements are filled, but the second time they're empty.

Any help is appreciated because this problem is holding up my work.

END{
if (lastpresstime < tothrs)
   {
   diffhr = tothrs - lastpresstime
   for (i=lastpresstime+1;i<=tothrs+1;i++)
      {
      xpressinter[i]=diffhr
      xpressrecords[i]=diffhr
      xipress[i]=lastpress
      xpressflag[i]="R"
      printf("PRS xipress[%4d] =%6.1f\n",i,xipress[i]) > "ncdcfm3.prs"
      printf(" xipress[%4d] =%6.1f%1s\n",i,xipress[i],xpressflag[i])
      }
   for (i=1;i<=tothrs+1;i++) printf("PRS xipress[%4d] =%6.1f\n",i,xipress[i]) 
   }
