This video gives basic information on Using the RETC "Conditional Return Back to Call" instruction in the Do-more Designer software. It presents information that is commonly missed by users. This WILL NOT be a complete tutorial for the instruction but rather a supplement to the help file and customer experience.
This instruction is used to mark the end of execution in a subroutine. How this differs from the Regular return instruction is that it allows for conditional contacts on the rung in prior to the instruction. This will be useful if you want to skip some code in your subroutine. If do you use a Conditional return in your subroutine, your subroutine still must have at least one RET instruction per subroutine.
