Abstract
A portable terminal machine which controls the execution of a downloaded program depending on a usage time limit when a sub program downloaded from a video game machine is stored in the storage device, the time of communication with the video game machine obtained from the clock is recorded in the sub program as a time stamp. At the time of the startup of the sub program, the portable terminal machine calculates the usage time limit based on the time of communication and compares this usage time limit against the current time obtained from the clock and stops the startup of the sub program if the usage time limit has been exceeded.
