COBOL bridge for NodeJS 介绍
COBOL bridge for NodeJS 可以让你在 Node.js 里面运行 COBOL 代码。
代码示例：
// Dependencies
var Cobol = require("cobol");
// Execute some COBOL snippets
Cobol(function () { /*
IDENTIFICATION DIVISION.
PROGRAM-ID. HELLO.
ENVIRONMENT DIVISION.
DATA DIVISION.
PROCEDURE DIVISION.
PROGRAM-BEGIN.
disPLAY "Hello world".
PROGRAM-DONE.
STOP RUN.
*/ }, function (err, data) {
console.log(err || data);
});
// => "Hello World"
Cobol(__dirname + "/args.cbl", {
args: ["Alice"]
}, function (err, data) {
console.log(err || data);
});
// => "Your name is: Alice"
// This will read data from stdin
Cobol(function () { /*
IDENTIFICATION DIVISION.
PROGRAM-ID. APP.

FILE-CONTROL.
SELECT SYSIN ASSIGN TO KEYBOARD ORGANIZATION LINE SEQUENTIAL.
DATA DIVISION.

disPLAY "Write something and then press the <Enter> key"

READ SYSIN
AT END SET EOF TO TRUE
END-READ
END-PERFORM
CLOSE SYSIN
STOP RUN.
*/ }, {
stdin: process.stdin
, stdout: process.stdout
}, function (err) {
if (err) {
console.log(err);
}
});
// => Write something and then press the <Enter> key
// <= Hi there!
// => You wrote: Hi there!
// => ------------
