Data Language/1(DL/1)
1. The IMS/VS data manipulation language—a common high-level interface between a user application and IMS/VS. It is invoked from PL/1, COBOL, or Assembler language by means of ordinary subroutine calls. DL/1 allows a user to define data structures, relate structures to the application, load structures, and reorganize structures.; IBM的虛存信息管理系統(tǒng)(IMS/VS)的數(shù)據(jù)操縱語言,是用戶應(yīng)用程序與IMS/VS之間的一個 高級公用接口,通過普通的子程序從PL/1、COBOL或匯編語言調(diào)用。DL/1允許用戶定義數(shù)據(jù)結(jié) 構(gòu),將結(jié)構(gòu)與應(yīng)用程序聯(lián)系起來,裝入結(jié)構(gòu)及重新組織結(jié)構(gòu)。 2. A data base access language used under VSE and CICS/VS. | 在虛存擴(kuò)充系統(tǒng)(VSE)和虛存用戶信息控制系統(tǒng)(CICS/VS)下使用的一種數(shù)據(jù)庫存取語言。
