Hmm... I tried to change the value of symbol type to real for the source and target addresses, but it doesn't allow me to Eg. MOVL D100 D102 Under "Edit Instructions", I clicked on the "..." of D100, its originally displayed as CHANNEL for "symbols of type" and i changed it to REAL, but after clicking ok, it still doesn't register my action. Ialso tried "edit symbol" and tried changing CHANNEL to something else, but it says only CHANNEL and BOOL are allowed. Is there any other place that needs to be changed"
