I want to explain to someone with follows expression.
But I'm not sure this expression is correct or not.
"In case of no need to make into a program." and "In case of need to make into a program."
In case of no need doesn't sound like very natural English to me. I think it would be better if you said:
In case there is no need
Also, to make into a program doesn't sound very natural, either. I think it would be better to say:
to make a program
to make «something» into a program
Also, build might be a better verb than make. The very write could work, too, if you are talking about a computer program.
