PURPOSE:To erase the token of only a specific process without interfering with another process by instructing a certain specific part of a circulation system as to the use inhibition of a color, discarding a token of the color at the time of arrival at the specific part, and erasing all tokens and then registering the color in a free color control stack. CONSTITUTION:The specific part (e.g. link memory part 5) of the circulation system discards all tokens of the color reaching the part. Namely, the novel token of the color does not circulates in the circulation system. Tokens of the color which remain in a matching store part 1 and the queuing memory 41 of a structure memory part 4 are all erased. Consequently, all the tokens of the color in a data flow computer are erased. Further, the emptiness of the color is registered after said processing, and then normal operation is performed in subsequent processes even if the color is used newly.
