1.13 Call Subroutine<br />

A subroutine is a set of instructions that are located after the End Program instruction.<br />

Call Subroutine causes the machine to jump to a specified memory address and execute<br />

the instructions found there using coordinates specified at the Call Subroutine instruction.<br />

When the End Program instruction for the subroutine is reached, program execution will<br />

continue at the address immediately after the Call Subroutine instruction.<br />

The Call Subroutine function is most useful to repeat a pattern anywhere on the workpiece,<br />

as opposed to the Step & Repeat function where the pattern must be repeated in<br />

straight lines, at fixed distances <strong>fr</strong>om each other.<br />

The following example illustrates the use of the Call Subroutine instruction.<br />

explanation follows.<br />

An<br />

1 Line Speed = 20<br />

2 Call Subroutine (X1,Y1,Z1) address 7<br />

3 Call Subroutine (X2,Y2,Z2) address 7<br />

4 Call Subroutine (X3,Y3,Z3) address 7<br />

5 Call Subroutine (X4,Y4,Z4) address 7<br />

6 End Program<br />

7 Line Start (Xs,Ys,Zs)<br />

8 Line End (Xe,Ye,Ze)<br />
