Resets transaction-begin pointer.
Use the command PURGE SITE or PU SIT to automatically reset the transaction pointer to one greater than the last transaction number. This is handy to use in a command file that contains PRINT TRANSACTION to print the transaction, and PURGE SITE to reset the transaction-begin pointer.
Note that you will ordinarily use the PURGE SITE command only if you are manually printing transactions and using the printed record as a basis for billing.
