我在 cygwin 终端中使用 OpenCOBOL 来编译这个程序，该程序应该从输入文本文件中读取并将其打印到格式化的输出文件中。当我尝试编译时出现此错误:
programonerjm.cbl:13: Error: syntax error, unexpected "SOURCE-COMPUTER", expecting "end of file"
我也不完全确定我的程序划分是否正确。
有人可以告诉我我做错了什么吗？我知道这可能是一个小错误，它让我发疯。

最佳答案
鉴于示例中的源代码，我在 GnuCOBOL 1.1 中收到以下错误(至少更新到此版本):
PROGRAM1.cob:58: Error: syntax error, unexpected '('
指的是VALUE('PAGE 0X'). ，我相信您会自己解决这个问题。
使用 GnuCOBOL 2.0 rc-1 编译器错误消息为:
PROGRAM1.cob: 58: error: syntax error, unexpected (
PROGRAM1.cob: in paragraph '100-MAIN-MODULE':
PROGRAM1.cob: 119: warning: ignoring redundant .
PROGRAM1.cob: in paragraph '120-READ-FILES':
PROGRAM1.cob: 137: error: unknown statement '130-PRINT-HEADERS'
您可以忽略“忽略冗余”消息或修复它(这只是一个警告，因为这可能指出问题 - 但您没有任何问题)。为了遵循程序其余部分的风格(并编写看起来不太像 COBOL-74 的代码)，我建议删除 PERFORM 之后的句点。 100-MAIN-MODULE 中的语句.
第 137 行在段落名称后面缺少一个句点(这同样适用于以下段落名称，但解析器当前无法从“未知语句”中恢复，因此您只能一一看到)。
下一个错误将是:139 接下来将发出:
in paragraph '130-PRINT-HEADERS':
139: error: 'NUM-PAGES' is not defined
in paragraph '160-CLOSE-ROUTINE':
167: error: 'INVENTORY-REPORT' is not a file name
要么重命名NUMBER-OF-PAGES中的var(我假设你的意思是WORKING-STORAGE)或在引用文献中。
CLOSE应使用文件名(在本例中 OUTPUT-INV-REPORT )而不是记录名称( INVENTORY-REPORT )。
这解决了语法问题。
附加提示:而不是
MOVE HEADER-LINE-ONE TO INVENTORY-REPORT
WRITE INVENTORY-REPORT
AFTER ADVANCING 1 LINE
您可以省略额外的 MOVE (无论如何，它都是在内部完成的，但它看起来更好；-)并明确表示这仅针对 WRITE 完成。 :
WRITE INVENTORY-REPORT
FROM HEADER-LINE-ONE
AFTER ADVANCING 1 LINE
