GENUUID 是 IBM 提供的过程。我可以找到从RPG调用GENUUID的示例，但需要在名称中添加_（下划线） EXTPRC('_GENUUID')
但我不知道如何在 COBOL 中执行此操作。
我尝试在 COBOL 调用命令中使用下划线，编译结束时出错，提示程序名称无效。
感谢任何帮助。谢谢！
请注意，在 v7.3 中，IBM 增强了 GENUUID 以支持类型 4 UUID。如果您想生成类型 4 UUID，请使用此模板（我认为，我的 COBOL 非常生锈，从未在 IBM 中端系统上使用过）。请注意，COBOL 不支持 1 字节二进制文件，因此
pic x(1)x'04'version 01 uuid-t is typedef.
05 bytes-in pic 9(9) usage comp-4.
05 bytes-out pic 9(9) usage comp-4.
05 version pic x(1).
05 reserved pic x(7).
05 uuid pic x(16).
