How to call a function with argument, without print?

[ecco]

Hi everyone! 

This is my first post. I am new to BasiEgaXorz but not new to programing. I usally do C# and javascript. 

By reading the documentations, looking at examples and the forum I learned that I can call a function like this: 

 emptyFunction

declare sub emptyFunction()

print "just an empty function"

end sub  

or with an argument, like this: 

print mySubFunction&("hello!")

declare sub mySubFunction(mystring as string)

print "the string is: ";mystring$; 
end sub   
 
But is there any other way to call a function with an agrument other than print? I seen gosub or goto, but I get errors when I try the following:

someFunction&(99) 'Error: Cannot identify instruction/Subroutine!

goto someFunction&(99) 'Error: Label does not exist!

gusub someFunction&(99) 'Error: Label does not exist! 

declare sub someFunction(value as integer)

print value

end sub

Thank you

You can call a subroutine that uses parameters like this:

	colorPrint 1,"hello"
	end
	
declare sub colorPrint(color as integer, text$ as string)
	ink color
	print text$
	exit sub
end sub

Remember, there's a difference between a function and a subroutine.

What Pico shows you is a subroutine - a routine that doesn't return a value. Functions work very similar:


 b = MyFunction(2)
 print b  ' Should be 4

declare function MyFunction (arg as integer) as integer
  a = arg * 2
  return arg
end function


Exit Sub and Exit Function aren't needed unless you have logic branches that need to return a value and/or exit the function/sub before reaching the end, otherwise it doesn't do anything useful
