Macro B programmers, a syntax question

[Fred10]

A fellow programmer found these in a macro that came with a grinder w/ a 31i control, I was asked what they are.

 

"||" and "&&",  are logical "or" and "and" statements in C++ and some other languages. They used as such in the macro I was asked to look at. Has anyone seen any thing in a Fanuc manual that says they are implemented in Macro B? The macro works, indicating they are implemented in the control for grinder, but where else?

In the FANUC Common to Lathe and Machining Center Operator's Manual  Custom MACRO section the "Arithmetic and Logic Operation" sub section AND OR are listed.
