Oracle - Calling a parameterized function in a SQL Statement

I have a function named MyFunction

MyFunction has two input parameters.

A working SQL call to a function named Function2 with one parameter exists.

MyFunction has 2 parameters instead of 1.
a.Col1, b.Col1

nvl(Function2(a.Col1),' ') AS myComments,

What is the syntax for 2 parameters?

nvl(MyFunction(a.Col1),' ',???) AS myComments,

??? MyFunction(b.Col1)

Parameters are comma separated:
MyFunction (param1, param2)

If one of the parameters is the result of function2, so be it:
myfunction(nvl(Function2(a.Col1),' '),'someotherparam')

From the description I do not understand what you are asking.

if you're trying to wrap both in nvl:

myFunction (
                             function2(a.col1), ' '
                    nvl(b.col1, ' ')

=NVL(   MyFunction (a.Col1, b.Col1)   , ' ' )

calling a function needing 2 parameters remains the same even inside NVL()

{+ edit}
OR, if you need to supply NVLs to the parameters themselves:

 MyFunction (  NVL(a.Col1,'')  , b.Col1)

 MyFunction (  NVL(a.Col1,'')  , NVL(b.Col1,'')  )
