FALLINTOFLST, Fall-through to a label with formallist is not allowed

Run Time/Compile Time Error: This error indicates that M code reached a label with a formallist by falling through from the previous label. When issued as a warning, it indicates the compiler determined such an error could happen. If the preceding line is the end of an embedded DO block, the compiler issues this error as a warning (if enabled) and ensures the block cannot fall through by explicitly inserting the impiicit QUIT. The warning and insert occur even if the line containing the argumentless DO associated with the block contains a terminating QUIT or HALT other than at the end of the block.

Action: Revisit your code to ensure that all invocations of labels with a formallist occur using a DO command or extrinsic function ($$).
