The START command syntax is:
STA[RT] [<address>]
where <address> is the starting address. If <address> is omitted, the
current PC content is used. In this case, the START command has the
same effect as the CONTINUE command.
When you specify an address, the START commandis thesameas executing
a Deposit to the program counter (PC) followed by a CONTINUE command.
That is, with the START command and an address as an argument, you
store an address in the program counter and then call for the system to
begin processing at that address.
