“	Functions must have a return type declared.

But currently we cannot write:
Code:

function  X() {
  function* MyProc() : sysword;
  if (MyProc() > 0) {}
  return true;
}

only allowed:
Code:

function  X() {
  function* MyProc() : sysword;
  gp_ax = MyProc();
  if (gp_ax > 0) {}
  return true;
}

And in this case type of 'gp_ax' used.
Also in usual functions we did not write type of them.

But if we really will use type of function then it of course good idea smile

I have been considering options of adding types to functions using a similar C like syntax, but this is on my "undecided" list for now.

It is possible to do it by analogy with:
Code:

function* MyProc() : sysword;

i.e. by this way:
Code:

function MyProc() : sysword; {
  sysword tmp;
// ..............  
  return tmp;
}

I thought about this way, but I was uncomfortable with the syntax

Code:

type; {

Options are:

1. Code:

function WINAPI MyProc(par1, par2, par3): sysword {
  //
}

2. Code:

function WINAPI MyProc: sysword(par1, par2, par3) {
  //
}

3. Code:

function WINAPI sysword MyProc(par1, par2, par3) {
  //
}

4. Code:

// c-type (not really suitable as i planned to use this format for very high level functions)
sysword WINAPI MyProc(par1, par2, par3) {
  //
}

5. Code:

sysword MyProc = WINAPI function(par1, par2, par3) {
  //
}

6. Code:

function WINAPI MyProc(par1, par2, par3) {
  //
}: sysword;

7. Code:

function:sysword WINAPI MyProc(par1, par2, par3) {
  //
}

As for me then #1 and #6 seems are good variants.
But advantage of #1 that we can distinguish type at the beginning of function.

Also i would like to pay attention that if we will add in future some other parameter then we maybe need to use semicolon. Like this:
Code:

function WINAPI MyProc(par1, par2, par3) : sysword; forward; noframe; some_other_param; ...; ...; ...; {
  //
}

OK maybe I will give it a try this way and see how it goes. I've added [post 1792] type #1 to my todo list.
