If "," used in the PRINT statement skips the cursor through the right edge of the screen, next position of the cursor is at the last column of the same line (LOCATE 49,Y), not at the next line (LOCATE 0,Y+1 or LOCATE TABSTEP,Y+1). Public key "43334DRM" reproduces the problem. No screen shot is available as I use the JP version "プチコン3号 SmileBASIC" and can't attach it.
