You can replace the if with match and make bitness an equ.
Code: Bitness equ 16 match =16,Bitness { BaseReg equ bp } match =32,Bitness { BaseReg equ ebp } |

Alternatively:
Code: Bitness = 16 if Bitness=16 label BaseReg at bp else label BaseReg at ebp end if |

Note that it has a potential problem that you cannot re-define BaseReg for other part of code when it is defined as a label. If such problem occurs, you can get around it with a simple "undefine" macro:
Code: macro undefine name { local new define name new } Bitness = 32 undefine BaseReg if Bitness=16 label BaseReg at bp else label BaseReg at ebp end if |

version with "equ" however is better because it doesn't refer only to addressing.
Code: push BaseReg ;push (e)bp is possible _________________ smaller is better |

Oh, you're right. This is a limitation of fasm 1 engine that I managed to get rid of in fasm g.
