Hi, I have an array in which the first element is either -0 or +0 (returned from the DateCalc function). How can I apply the flag value to all the values in the rest of the array.

I tried from the command line, but found a wierd quirk with -0. In order for it to work correctly, it looks like I need to use it as a string array.

perl -le '@B=qw(-0 4);$g=($B[0] lt 0?-1:1); 
            printf"%s\n" x 3,$B[0],$g,$B[1]*$g'
-0
-1
-4

perl -le '@B=(-0,4);$g=($B[0] < 0?-1:1); 
          printf"%s\n" x 3,$B[0],$g,$B[1]*$g'
0
1
4

Can the map or regex substitute command take the sign value and apply it to the remainder of the array?

Thanks budman
