    The language I'm using for this external application is Rust, and more specifically I'm experimenting with Webassembly.

    Thank you in advance for your time and support with this request.

    Leo –

    If you're using YottaDB, just use the yottadb crate (https://yottadb.gitlab.io/Lang/YDBRust/yottadb/index.html). If that does not meet your needs, or you run into any problems, please create an Issue at https://gitlab.com/YottaDB/Lang/YDBRust/-/issues

    Leo,

    The following is a very simple method to call a GT.m or YottaDB routine from node.js.

    It works generally like calling GT.m or YottaDB from a shell script.
    Setting up the environment variables, then calling MUMPS and ROUTINE with: mumps -run INDEX^WBDICT

    What the MUMPS ROUTINE Writes gets sent to stdout and displayed on the web page.
    ----------------------------------------

    var express = require("express");
    var app = express();
    var exec = require("child_process").exec;

    process.chdir('/home/biskate/wbdict');
    process.env.gtm_dist = '/usr/lib/fis-gtm/V63012';
    process.env.gtmroutines = './(./) /usr/lib/fis-gtm/V63012'; process.env.gtmgbldir = './gtm.gld';
    process.env.PATH = process.env.PATH + ':/usr/lib/fis-gtm/V63012';

    app.get('/index', function (request, response) { index(request, response); });

    var server = app.listen(8081, function(){ console.log(Date() + ": Server has started."); });

    // Function to Call a M Routine through the Linux shell.
    // To display the index web page.
    function index(request, response)
    {
    cmdLine = "mumps -run INDEX^WBDICT";
    exec(cmdLine, {maxBuffer: 1024 * 3000}, function(error, stdout, stderr)
    {
    response.writeHead(200, {"Content-Type": "text/html"});
    response.write(stderr);
    response.write(stdout);
    response.end();
    });
    }

    Thank you for your replies.
    I think I have a good starting point to work on a solution/example.

    Hello Leonardo!

    Can You do HTTP-Requests? In this cas you'll have a modern client-server-solution. You can try my FastCGI-Backend
    which connects YottaDB to HTTP.


    https://github.com/informatik-aalen/FastCGI-for-YottaDB

    Samples included.

    Greetings

    What's it worth to have one? $5, $10 ... $50 per copy...
    Am thinking about providing a GUI capability for Mumps users. The question is: Will anyone pay for it?
