Forum Index : Microcontroller and PC projects : does Basic run subscript expressions ?

Just wondering, does Basic accept subscript expressions ? Eg where gunge is an array foo = gunge(6*j+2) To me they seemed to be best avoided but they were in use to some extent. I am wondering whether to add the capability to my interpreter (mainly as a result of a boredom tsunami  )then again it should also handle COMMON named blocks, adding them would probably be pointless but hey.. |

Yes, you can certainly use expressions rather than a numeric constant as an index. It's a major benefit of arrays. |

Just be aware of the execution sequence. Sometimes you need brackets to force an expression to work in the way that you want. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

You need inner brackets depending on math or logic to get the correct result. |
