Accessing the Terminal Commands Terminal Commands
Move POinter (M PO)
The TopKAT transaction file uses a circular memory storage technique that keeps accessible
the last several hundred (at least 1650) transactions. There are two pointers in the transaction
file: a safe pointer and a next transaction pointer.
• The safe pointer marks the beginning of the file location. The safe pointer remains fixed
unless you move it using the Move Trans Pointer command.
• The next transaction pointer marks the next transaction to be assigned location. The next
transaction pointer moves ahead each time a new transaction is received.
When you do a Print Transactions terminal command, your transaction printout begins at the
safe pointer and ends with the last transaction before the next transaction pointer.
When the next transaction pointer reaches the safe pointer, and memory-full protection is
enabled, the MEMORY FULL message displays and no more transactions can be stored or
created. If memory-full protection is disabled, the safe pointer bumps up one transaction slot at
a time as each new transaction is received thus overwriting existing transactions in memory.
To ease a memory-full condition, you can use the Move Trans Pointer command to move the
safe pointer forward towards the next transaction pointer thus freeing up transaction storage
space for new transactions. Before doing this; however, you need to poll your transactions.
You can poll using the print transactions PR TR command. Transactions are read from the safe
pointer to the next transaction pointer. Then use the MO PO command to relocate the pointer
and make room for additional transactions. You can also poll using a Gasboy PC package.
Transactions are copied to a file on the PC and the safe pointer is automatically moved to the
next transaction pointer to free up memory for more transaction storage.
