As I suppose, code should like this: A F43.1 (one scan signal) l FW40 SLW 1 T FW40 segment end. But when I write SLW 1 line, apperad the next error message: 1007: OP.violates lang. subset. What's it mean? And where do I make mistake? Thank you in advance.

Beside this i want to say that the A F43.1 instruction would not work as condition. The next statements will be executed, whether F43.1 is false or true. Kind regards, BV
