WELCOME

I've never done a post related to how the SCL debugger is meant to be used. Here it is - following some recent questions from colleagues. You can imagine the SCL debugger as a simplified version of the debugger you have in Visual Studio. It only covers the basics. As you might happen to know Visual Studio works in its own process and attaches to the process running your code when you debug. Usually you pick the process from a list and then select the debug engine (native, m

The unconditional jump instruction is here. It is strange to announce such a trivial thing but it was a real challenge to implement. What makes it hard? It is intended to work on a flattened program tree. Flattening the program tree is the actual problem. In version 2512 we have it working with some limitations. But lets start with a short introduction. 'Goto' is a statement that is often avoided since it tends to make the code unreadable/unmaintainable if overused. Typ

Lately we are working on the topic of material handling. One of our goals was to generate a pick and place robotic operation based on user input. The user is supposed to select the object to be picked, the frame to be used when picking it and the pose of the tool when doing the pick. Then the user selects a frame representing the place location and the pose of the tool when doing the place. In addition the user can specify start/end robot home positions (poses) and approach/d
