Comment, remark
The instructions in the blocks of a program can be explained using comments (remarks). A
comment always starts with a semicolon “ ; ” and ends with end-of-block.
Comments are displayed together with the contents of the remaining block in the current
block display.
Messages
Messages are programmed in a separate block. A message is displayed in a special field
and remains active until a block with a new message is executed or until the end of the pro-
gram is reached. Max. 65 characters can be displayed in message texts.
A message without message text cancels a previous message.
MSG(“THIS IS THE MESSAGE TEXT”)
