Hi there, if that's the case then to parse all the fields something like:

printf "|%4s|%4s|%2s|%2s|%2s|%3s|\n",
   map {s/\s+//g;$_} unpack "A11A5A3A3A3A*" for <DATA>;

__DATA__
      1234 2321 0      45    1st
      2122 sdsa 0   0  34    
      2313 dsad        43    2nd    
      1232 ffff 0   0        1st
      3213 sadf     0  34    
      2133 dada 0            2nd

Would print:

|1234|2321| 0|  |45|1st|
|2122|sdsa| 0| 0|34|   |
|2313|dsad|  |  |43|2nd|
|1232|ffff| 0| 0|  |1st|
|3213|sadf|  | 0|34|   |
|2133|dada| 0|  |  |2nd|
