Language Concepts Report File A report file is an output file having sequential organization. A report file has a file description entry containing a REPORT clause. The content of a report file consists of records that are written under control of the RWCS. A report file is named by a file control entry and is described by a file description entry containing a REPORT clause. A report file is referred to and accessed by the OPEN, GENERATE, INITIATE, SUPPRESS, TERMINATE, USE BEFORE REPORTING, and CLOSE statements. Special Register PAGE-COUNTER The reserved word PAGE-COUNTER is a name for a page counter that is generated for each RD entry in the report section of the Data Division. The implicit description is PIC 9(6) BINARY. The value in PAGE-COUNTER is maintained by the RWCS and is used by the program to number the pages of a report. PAGE-COUNTER can be referenced only in the SOURCE clause of the Report Section and in Procedure Division statements. (See the section PAGE-COUNTER Rules later in this chapter.) Special Register LINE-COUNTER The reserved word LINE-COUNTER is a name for a line counter that is generated for each RD entry in the report section of the data division. The implicit description is PIC 9(6) BINARY. The value in LINE-COUNTER is maintained by the RWCS, and is used to determine the vertical positioning of a report. LINE-COUNTER can be referenced only in the SOURCE clause of the report section and in Procedure Division statements; however, only the RWCS can change the value of LINE-COUNTER. (See the section LINE-COUNTER Rules later in this chapter.) For OSVS only: Special Register PRINT-SWITCH The reserved word PRINT-SWITCH is a name for a register whose value may be set to non-zero in the course of a USE BEFORE REPORTING declarative procedure. This has the effect of suppressing printing of the corresponding report group. Subscripting In the Report Section, neither a sum counter nor the special registers LINE-COUNTER and PAGE-COUNTER can be used as a subscript.
