How can I use a boolean to determine whether to incr or decr a variable?

[rkoivisto]

I need to use a switch on the front panel to determine whether the program increments a variable or decriments the variable. I'm not sure how to do that. What I would like is an enable on a +1 or -1 function.

You could use a case structure with a boolean input.  Put the decriment in one case, and the incriment in the other.

Simple.
