Thanks Levente. I tried the above with a Foundation function, with no
success:

After I put a link to the Foundation lib in the VM's Resources folder, I
compiled:

CarbonFunctions>>NSMakeRectWithX: xFloat y: yFloat w: widthFloat h: hFloat
	<apicall: void* 'NSMakeRect' (float float float float) module:
'Foundation'>
	^self externalCallFailed

DoIt:
CarbonFunctions
	NSMakeRectWithX: 0.0
	y: 0.0
	w: 100.0
	h: 100.0.

Error: Unable to find function address
