Hi There, The following program: NOTE_B0 = 0 .START: EQUB NOTE_B0 .END: SAVE "PROG",START,END will not compile with the error: test.asm:3: error: Symbol not defined. EQUB NOTE_B0 ^ Is the word NOTE special? Thanks for any help - PJ |

No, but the function NOT is  BeebAsm is interpreting that line as EQUB NOT(E_B0), i.e. looking for a symbol called E_B0. BBC BASIC is the same - that wouldn't have allowed you to have a variable 'NOTE' either.In lower case, 'note' would be fine. However you have found a bug, in that the variable declaration on line 1 is working without problems. I'll have to have a look at that. |

I'm thinking that perhaps the solution here is to require all function keywords to be followed directly by an open bracket, i.e. Code: NOT(x) rather thanCode: NOTx This is different to BBC BASIC, in which most functions need not enclose their parameter in brackets. But it might fix these kind of problems (in particular those caused by starting variables with LO and HI). Any thoughts, anyone? Would this break anyone's source code? |

I like the parenthesis suggestion! If this change breaks any existing code, it's an easy fix  I've been bitten by this previously - I believe it was some label starting with LOOPBlahBlah, being reported as not being defined, when it clearly was! (I assumed LOOP was somehow causing grief - the LO keyword never dawned on me  ). Once I converted this code (not mine!) to lowercase (my preference), the problem went away. Personally, I don't really mind either way. I know what to look out for now .
