Function calls function

[IvanCodin]

I am new to programming and often struggle with call flows in scripts. The question I have is this ....

Is it good programming practice for a function to call another function or should this be avoided. I always get stuck when trying to figure out the flow of script errors. I do understand functions run and return results or do specified things. What I struggle with is when I want to check the users input should I do it in the function or test all of the inputs after they have been entered by the user.

What is you learned opinions???

Thanks

Really only a function is useful if you will call it more then once

No learned opinion here, but functions calling other functions is normal and healthy in a well-coded script. As for your specific example, if you only have to code the check once in a particular function, there is no reason to break it out into a separate function. As soon as you find yourself typing the same check in again anywhere else, it's time to put it in a function of its own.
