create an array of numbers in awk
Hi !

I try to create an array of a large amount of numbers in increasing order from 1 to 10,000 (or even infinity).

Is there an easier way to do that than writing:
Code:
split("1,2,3,4,5,6,7,8,9,10,11,12,13,14,..............,10000",numbers,",")

Doing something like:
Code:
split([1-10000],numbers)

Thanks !

I guess you have your reasons, but I don't see the point of an array of sequential numbers.

Code:
awk '
   BEGIN {
      for( i = 1; i <= 10000; i++ )
         numbers[i] = i;
   }
