im sorry i just dont understand this part of the tutorial

6. read the long int number on the Data Inspector, this is how many bytes are after it. There will be a 4-byte long- int after each header telling how many bytes come after it.
7. Put cursor on last byte of the long int.

here's my data inspector

word[+]: 7516
interger[+]: 7516
longint[+]: 7516
ieee single: (random numbers)
binary: 10101010(something like that)

what byte is the last of 7516? i got this after putting my cursor here: MODL\ does it want me to put the cursor 6 bytes away from the \ ?
so basically what im asking is where does it want me to put my cursor(in layman's(spelling?) terms)
