INT 15 - TopView - "ISOBJ" - VERIFY OBJECT HANDLE
AX = 1016h
ES:DI = possible object handle
Return: BX = FFFFh if ES:DI is a valid object handle
0000h if ES:DI is not
Note: under DESQview versions prior to 2.50, an object handle is always a
pointer to the object; for versions 2.50 and up, only task handles
are always pointers (other handles may consist of an object number
and offset into DESQview's common memory)
SeeAlso: AX=DE2Bh
