How to contribute

The easiest way to contribute is by contributing either an RPGLE built-in function or a system API.

Contributing a BIF

Inside of the Runtime/Functions/ directory is a folder called BIF. Each function inside of the BIF folder inherits the Function class which takes an object[] parameter, which is passed in from the RPG application.

The Function class has an Execute method which is the invoked method when the BIF is invoked from the RPG application:

class Trim : Function
{
    public override object Execute(object[] Parameters)
    {
    }
}

The Execute method can return any regular C# type and it'll be returned into the RPG application as expect. See some of the following examples:

• %trim
• %lookup
• %dec

The last part to making the BIF work is adding it to the Functions list in Functions.cs.

Don't forget to write unit tests for your new BIF too.
