The JOIN command operates according to the current cursor location in the edit area. If the line resulting from the join is too long to fit onto the current line, the extra characters are wrapped around to the next line.
The JOIN command may be entered in the input area and executed at the cursor position in the display area, as described in the example below. However, it is normally more convenient to assign a PF key to the command.
The JOIN command complements the SPLIT command.
