When you attempt to type beyond the boundaries of the memo window, one of two things will happen. If the programmer has defined a larger maximum memo pad size than the window and the window is not yet at the boundary, the window will scroll to reposition the cursor closer to the center of the window. If the window boundary coincides with the absolute memo pad size boundary, then the cursor will wrap to the first column on the next row, provided you are not also at the bottom limit of the memo pad. If so, instead of wrapping, the cursor will just stop.
