object command ?

ok so after emailing blitz research they were kind enough to give me a work around:
Extern
Function bbHandleToObject:Object( handle )
Function bbHandleFromObject( obj:Object )
End Extern

Type MyType
Field x=1234
End Type

Local t:MyType=New MyType

Local h=bbHandleFromObject( t )

Local p:MyType=MyType( bbHandleToObject(h) )

Print p.x


Now Ive encorperated that into my code and it works but I need to do the following:

Blitz3d
Actor.ActorInstance = Object.ActorInstance(Int(SafeSplit$(Params$, 1, ",")))

now in Blitzmax I have this:
Actor:bbActorInstance = bbActorInstance(bbHandleToObject(A))

but I cannot figure out how to still use
Int(SafeSplit$(Params$, 1, ","))

Any suggestions would be great thanks
