This is an adaptation of code from the Example folder, clunky but works, I'm sure there'll be more elegant solutions forthcoming

include "NSLog.incl"

local fn MyComparator( os as OrderedSetRef, obj1 as CFTypeRef, obj2 as CFTypeRef ) as NSComparisonResult

'~'1

NSLog(@"%@,%@",obj1,obj2)

NSComparisonResult result = fn StringCompare( obj1, obj2 )

end fn = result

void local fn DoIt

'~'1

OrderedSetRef os = fn OrderedSetWithArray( @[@2,@44,@11,@99,@35] )

NSLog(@"%@n",os)

CFArrayRef array = fn OrderedSetSortedArrayUsingComparator( os, @fn MyComparator, NULL )

NSUinteger count = fn ArrayCount(Array)

NSLog(@"n%@ count= %d",array, count)

NSLog(@"Max Number= %@", fn ArrayObjectAtIndex( array, count-1))

end fn

fn DoIt

The following works in Objective-C

But how is this done in FutureBasic? (without using a C Function)

NSArray *unsortedArray = @[ @2, @44, @11, @99, @35 ];

NSNumber *maxNumber = [unsortedArray valueForKeyPath:@"@max.self"];

NSLog(@"%@", maxNumber); // 99
