ok, This is the problem: I need to create thousands of "numbers" made of numbers and letters, so that when I get to "9" the number continues with "a, b, c, ..." so i need something like this in output:
0001 0011
0002 0012
0003 0013
0004 0014
0005 0015
0006 0016
0007 0017
0008 0018
0009 0019
000a 001a
000b 001b
000c 001c
0010 etc...
do you have some idea to creare this with a batch file (output .txt) or with excel?
