Access 10,000 Bytes Example

For example, if you want to access 10,000 bytes:

Step 1:

Actual_Bytes_to_RW = 10,000 + (TRN (10,000/442) * 8) + (If the MOD

(10,000/442) > 0 then 8 else 0)

= 10,000 + 22(8) + 8

= 10,184

Step 2:

450[(TRN(10,184/450)) + (If the MOD (10,148/450) > 0 then 1 else 0)]

= 450 [22+1]

= 450(23)

= 10350 bytes

You need to increase the arrays to a minimum of 10,350 elements. Do not

place this value in the Actual_Bytes_to_RW. This value is calculated when a

file command is executed.
