In Blitz, handles are always integers. (There are only a few built-in types in Blitz anyway.)

Also, whenever a variable (or return type) is declared without specifically referencing the type, it is assumed by Blitz to be an integer. In other words, these examples are all the same:

Function draw(img)
    DrawImage img,0,0
End Function

Function draw%(img%)
    DrawImage img,0,0
End Function

Function draw%(img)
    DrawImage img%,0,0
End Function

Function draw(img)
    DrawImage img%,0,0
End Function

...etc
