How can I check if symbol is defined in FASM? (like #ifndef in C++)

For the label or numerical constant (which are defined at assembly stage) it would be:
Code: if defined symbol ; ... end if This operator checks whether the symbol is defined anywhere in source (with prediction), not only whether it was defined earlier. Read part 4 of this article for more details about this specific problem. For the symbolic constant (defined with EQU, processed at preprocessing stage), it can be something like this example from the manual: Code: match =TRUE, DEBUG { include 'debug.inc' } to check for specific value; or something like this: Code: match =DEBUG, DEBUG { } to check whether DEBUG constant was not defined at all. |
