Since Livecode version 7.0 it’s also possible to pass an array element by reference and that also works with “Dispatch”. Example: on mouseUp Put "27" into tTemp["tKey"] Dispatch "AdjustSetting" with tTemp["tKey"] # Now tTemp["tKey"] = 62 put tTemp["tKey"] end mouseUp on AdjustSetting @pSetting Add 35 to pSetting end AdjustSetting
