what if a function requires multiple argument-based refinements?
[1/4] from: princepawn:lycos at: 28-Aug-2000 7:43
This is a bit of an abstract question by a person who is 1/3rd of the way through the
McGraw text, but I just keep popping with questions.
What if I had the following:
>> f: func [ a /ref1 arg1 /ref2 arg2] [ either ref2 [ print "ref2" ] [ print "no ref2"
] ]
>> f/ref1 3 /ref2 4 1
no ref2
== 1
>>
how could I call the function "f" to make use of both refinements?

The template for the function call would be:
f/ref1/ref2 <a> <arg1> <arg2>
So, try:
>> f: func [ a /ref1 arg1 /ref2 arg2] [ either ref2 [ print "ref2" ] [
print "no ref2" ] ]
>> f/ref1/ref2 3 4 1
ref2

Not sure if this is what you mean or not
f/ref1/ref2 'a 'arg1 'arg2
or
f/ref2/ref/1 'a 'arg2 'arg1
Just make sure the arguments are in the order of the refinements.

Hi,
Like this:
f/ref1/ref2 3 4 1
Hope that's what you want...
Anton.
