 Welcome to this welding module on calls and unconditional jumps. In this module, you'll explore how to use calls and unconditional jumps when using the robot. These commands are used throughout your lab work and are also common in industrial applications. A call statement transfers control from one program to another within the original program. In this example, main program has a call command. When this line executes, the robot leaves the current program and runs the T-joint program completely. When program T-joint finishes, the cursor returns to the original program, which is one line below that call statement. A jump and a label are two commands that work hand in hand. The jump moves the cursor to a new location in the program. The label is the destination for the jump. This example program shows two calls and an unconditional jump. It can be used as a reference tool when doing your lab work. Line 1 is a motion command that moves the robot to its home position. Line 2 is a label which is a destination for a jump command used later in the program. Line 3 calls a program named T-joint. When this line executes, the robot completely leaves the current program and runs the T-joint program. When program T-joint finishes, the cursor returns to the original program, which is one line below that call statement. Line 4 calls a program named L-joint. When this line executes, the robot completely leaves the current program and runs the L-joint program. When program L-joint finishes, the cursor returns to the original program, which is one line below that call statement. Line 5 is a jump command. The destination is label 0001. When this line executes, the cursor moves back up to line 2 of the program. As this example is written, this process will repeat itself over and over again. This program will only stop when an operator interrupts the sequence. Now, let's check your knowledge with a few questions. In this module, we explored how to use calls and unconditional jumps when using the robot. You've completed using calls and unconditional jumps.
