It was just a month back that i came across this language called “Lj4” and was a bit surprised to hear about this language for the first time .
I got a chance to know about the language when i was exploring Infor ERP .I am sure that there are many developers who might not be aware of this language too ..
Whats surprising is that just Google “Lj4” , and u might not even get a single result related to what i was looking for but instead one gets the links related to the LJ4 Printers , HP etc ..
You might get some info or links of Lj4 like Comprehensive Framework for Mobile ERP System (IEEE) and some companies implementing Infor :COM etc.
I couldn’t see the language even in the Wiki too .
So how did i get started with the Lj4 without any help from google search ?? . Guess what? , there is a little documentation from Infor about this language . just little ..
Now , getting back to the language .
Lj4 is closely related to other 4GL language like Visual Basic for Applications (VBA) ..
So , syntax wise when i saw the Lj4 source code , i was able to read it better since i knew a bit of VB too 🙂
What is the Development Environment for Lj4 ??
If a Infor ERP COM is installed on the machine , one can start the Lj4 Development by starting the Infor Dialog Manager .
Infor ERP COM Dialog Manager is an IDE for Infor ERP COM. One can customize the objects in infor of a customer’s machine using the Infor Dialog Manager .
The Data in Infor can be accessed via a set-oriented interface called VQL ( Versatile Query Language ) somewhat similar to SQL but works differently .
I know there is nothing in Depth of Lj4 being addressed in this blog post , but the intention of this post was just to make myself and my visitors aware of this language .
What are the other languages that you are aware of ?? .
