标签: sysin

我想在COBOL中读取STDIN(又名SYSIN)的行.现在我只想把它们打印出来,以便我知道我有它们.从我正在阅读的所有内容看起来应该可行:

IDENTIFICATION DIVISION.
PROGRAM-ID. APP.

ENVIRONMENT DIVISION.
INPUT-OUTPUT SECTION.
FILE-CONTROL.

    SELECT SYSIN ASSIGN TO DA-S-SYSIN ORGANIZATION LINE SEQUENTIAL.

DATA DIVISION.
FILE SECTION.

FD SYSIN.
01 ln PIC X(255).
    88 EOF VALUE HIGH-VALUES.
WORKING-STORAGE SECTION.

PROCEDURE DIVISION.
    OPEN INPUT SYSIN
    READ SYSIN
      AT END SET EOF TO TRUE
    END-READ
    PERFORM UNTIL EOF
        DISPLAY ln
        READ SYSIN
            AT END SET EOF TO TRUE
        END-READ
    END-PERFORM
    CLOSE SYSIN
    STOP RUN.

编译(使用open-cobol和cobc -x),但运行它我得到:

libcob: File does not exist (STATUS = 35) File : '' …
