标准输入流＆QUOT在设置外壳的控制break语句;排爆＆QUOT;退出COBOL程序 [英] Setting shell's control break statement in the standard input stream "EOD" to exit the COBOL program

问题描述

我想通过在EOD指定命令行提示值如下调用直通shell脚本COBOL程序。

I would like to invoke a cobol program thru shell script by assigning command line prompt values in the "EOD" as below.

#!/bin/bash
run pub/coblprog<<:EOD:
1
2
3
:EOD:

考虑一下，如果COBOL程序coblprog有4个命令行提示，并在运行时预计4输入命令行参数。我在EOD指定3提示值。由于COBOL有四个提示，但不EOD经过3个值，COBOL程序进入无限循环，预计第四提示值。

Consider if COBOL program "coblprog" has 4 command line prompts and expects 4 input command line arguments at runtime. I have specified 3 prompt values in the EOD. Since COBOL has four prompts but at EOD does passing 3 values , COBOL program is going into infinity loop to expecting the fourth prompt value.

我的要求是，我想之前所有的第二次提示值后设置一个shell的控制break语句（如下面）：EOD :.通过观察shell的控制语句的shell脚本应该异常终止。

My requirement is, I would like to set an shell's control break statement (like below) after all prompt values before second :EOD:. By seeing that shell's control statement the the shell script should terminate abnormally.

#!/bin/bash
run pub/coblprog<<:EOD:
1
2
3
exit 1
:EOD:

我已经有声明退出的脚本并运行，但没有运气..！请建议我很好的解决方案。

I have have exit statement in the script and run, but no luck..! Please suggest me good solution.

我执行在Linux上的脚本，COBOL程序是Micro Focus公司COBOL。

I am executing the script in LINUX, COBOL program is Micro Focus COBOL.

推荐答案

这行后＆LT的数据;＆LT;：EOD：到该行之前的1开始：EOD：输入到COBOL程序和不的外壳控制语句，因此在退出1 会的数据的，这可能不是你想要的。

The data from the line after <<:EOD: until the line just before the one beginning :EOD: is input to the COBOL program, and not shell control statements, therefore the exit 1 will be data, which is probably not what you want.

如果你想运行coblprog后shell脚本退出，然后将它放在开头的行之后：EOD：

If you want the shell script to exit after running coblprog, then place it after the line beginning :EOD:.

#!/bin/bash
run pub/coblprog<<:EOD:
1
2
3
4
:EOD:
exit 1
