How to print an array in defined order in AWK 3.1.3 -

i googled , find out after awk 4.0 can print array in defined order putting procinfo["sorted_in"] command right before loop. example procinfo["sorted_in"] = "@ind_num_asc" for( in array) print i, array[i] in awk 4.0.2, works. however, tried in awk 3.1.3 environment, did not work. version of awk not support function? how achieve goal in awk 3.1.3? just keep second array order numerical indices , keys first array values. can iterate through order in sequence , values of array : for (i = 1; < length(order); i++) { print order[i], array[order[i]] } when building order , may want check whether key present in array , prevent keys of array being shown multiple times.

the following code convert int bytes array. know int i right shifted 24, 16, 8 times , anded 0xff can't understand why these numbers used? private static byte[] inttobytes(int i) // split integer 4 byte array { // map parts of integer byte array byte[] integerbs = new byte[4]; integerbs[0] = (byte) ((i >>> 24) & 0xff); integerbs[1] = (byte) ((i >>> 16) & 0xff); integerbs[2] = (byte) ((i >>> 8) & 0xff); integerbs[3] = (byte) (i & 0xff); // (int j=0; j < integerbs.length; j++) // system.out.println(" integerbs[ " + j + "]: " + integerbs[j]); return integerbs; } // end of inttobytes() ok lets pretend have 32 bit binary number: 00001111 00000111 00000011 00000001 one byte equivalent 8 bits , therefore number above comprised of 4 bytes. to separate these bytes out need perform series of shift , and mask operations. for instance first byte (00001111) f
