Include Files .... inside a function

AFL Programming
1

I am having a lot of errors from an include file inside a function.

This would lead me to believe that #includes are not allowed inside a function, but I can not find any such prohibition in the help files.

Are #include files allowed inside functions?

It is allowed but it depends on what is content of include file.

So let's say your incude file's name is _test.afl
Within that AFL there is placed a variable "x" and a value such as 1 is assigned to it.

Now... to "Formula 156.afl" of upper picture there is added a function with #include line:

function fun_name()
{
  #include <_test.afl>
  
  result = x; 
  return result;
}

y = fun_name();
printf( "y is: %g", y );

If applying Formula 156 then there is no error but output of y = 1

Now what if we add a function to that include file _test.afl

4317

Then if still executing formula file "Formula 156" with same content as above then you will get error.

Why? Because it is not allowed to place a function definition within another function.

So if you do this considering content of _test.afl of upper case

function fun_name()
{
  #include <_test.afl>
  
  result = x; 
  return result;
}

Then it is same as doing this one

function fun_name()
{
	x = 1;
	
	function fun_name2( arg1, arg2 )
	{
		result = arg1 + arg2; 
		return result;
	}
  
	result = x; 
	return result;
}

and it is not allowed as well.

In general it is not good practice to add include file within function. Just avoid nightmare(s).
