custom functions

does mq4 allow complex functions? ie can i return more than just a simple type from a function(int, bool, double?)

iAlligator fillAlligator(int mode)
{
if (mode==MODE_GATORJAW)
{
return iAlligator(NULL,0,jaw_period,jaw_shift,teeth_period,teeth_shift,lips_period,lips_shift,MODE_EMA,PRICE_CLOSE,MODE_GATORJAW,0);
}
if (mode==MODE_GATORLIPS)
{
return iAlligator(NULL,0,jaw_period,jaw_shift,teeth_period,teeth_shift,lips_period,lips_shift,MODE_EMA,PRICE_CLOSE,MODE_GATORLIPS,0);
}

if (mode==MODE_GATORTEETH)
{
return iAlligator(NULL,0,jaw_period,jaw_shift,teeth_period,teeth_shift,lips_period,lips_shift,MODE_EMA,PRICE_CLOSE,MODE_GATORTEETH,0);
}
}

I'm not sure exactly what you're looking to do, but, you can return arrays as well. Rather, you can create a prototype function (void) and assign your values into an array which can be accessed by other functions.

Can you explain a little more of what you want to do?

NEVER MIND>.>>I SEE MY MISTAKE....I should be returning a double and not an ialligator...duh...

i want to create a function that returns an iAlligator type that accepts an integer variable _mode_ then based on which value is passed returns one of 3 ialligator indicators.

I had included the snippet for clarity. This will enable me to keep variable assignments under control and wont have the same code all over the place.
