SHOWM

The commands HIDEM (hide mouse) and SHOWM (show mouse) cause the mouse pointer
to be made invisible or visible respectively. Use of the ALERT command or other
AES routines causes the mouse pointer to be switched on, and, if not required,
it must be subsequently re-hidden with HIDEM.

During output to the screen with PRINT or the VDI or Line-A routines the mouse
pointer is automatically switched off, but afterwards returned to its previous
state.

Example:

    REPEAT
      IF MOUSEK=1
        SHOWM
      ENDIF
      IF MOUSEK=2
        HIDEM
      ENDIF
    UNTIL MOUSEK=3

--> The mouse pointer is activated by pressing the left button, and
    de-activated by pressing the right button. Pressing both simultaneously
    ends the program, when the 'Program End' alert box leaves the pointer
    visible.

Memo These are actually Line-A calls.
