Title: Do implied list processing system
Inventor: FUJII HITOSHI
IPC: G06F9/45
Filed: 1988-10-06
Abstract: PURPOSE:To reduce the number of actual running steps and to perform an output processing at high speed by reducing the call of an RTP by changing an input/output list to a linear DO implied list. CONSTITUTION:A source WRITE(1) [1(K)*J(K), K=1,N] is executed in a source program 1. At a DO loop developing part 211 in an object program generating means 21, the part of a DO implied list is developed in a DO text, and an object program 31 to store a value of I(K)*J(K) in work(K) according to a DO variable K is generated. At an output call part 212, an object program 32 to call the RTP is generated after information with respect to the type of the work, etc., is generated. As a result, the DO implied list linear to the DO variable can be generated by converting the input/output list from [I(K)*J(K), K=1,N] to [work(K), K=1,N], and a processing can be performed only one time of call of RTP according to a FORTRAN compiler. In such a way, it is possible to reduce the number of actual running steps and to perform the output processing at high speed.
