Title:
SYSTEM FOR PROCESSING CASE STRUCTURE CAPABLE OF SPECIFYING RANGE
Document Type and Number:
Japanese Patent JP2500515
Kind Code:
B2
Abstract:
PURPOSE: To output an efficient object without changing an order specified by an user at the time of processing a CASE structure capable of specifying a range.
CONSTITUTION: This system is constituted of a CASE structure processing part 1 provided with a next period judgement branching processing deciding part 11 for deciding an optimum branching destination when a block is not executed by recording even information for which large/small relation is compared with a value stored beforehand in the case of storing the value specified by a CASE sentense and a judgement branching processing generation part 12 for generating an intermediate code for branching to a corresponding CASE block when the judgement of the respective CASE blocks is true, and branching to the optimum branching destination obtained at the next period judgement branching processing deciding part when it is false. Thus, the output of the efficient instruction for which excessive judgement is not performed is enabled without changing the output order of the judgement for a CASE syntax capable of specifying the range.
