[net.micro.atari16] Cursors and *.PRG

harrison@utfyzx.UUCP (08/15/86)

If one names the program FOO.PRG, then default is no  cursor,  as
has  been  stated by many others.  Naming it FOO.TOS will turn on
the cursor, but if the program also contains  windows  and  other
GEM  stuff  from  the RSC set it will usually hang.  The solution
for me, where sometimes I'm using  windows  and  sometimes   just
naked   printf's   in   the  same program  is  to explicitly turn
the cursor on and off.  Also, GEM will fire up the  cursor  where
it was left last time, so I usually home it and clear the screen.
Then I can keep calling it FOO.PRG.  Example:

        /* GEM stuff */
        ....
        /* regular stuff begins */
        graf_mouse(M_OFF, 0L);  /* turn off mouse */
        Cconout('\033'); Cconout('H');   /* home cursor */
        Cconout('\033'); Cconout('J');   /* clear to end of screen */
        Ccconout('\033'); Cconout('e');  /* enable cursor */

        printf("Hello world.\n");

        Cconout('\033'); Cconout('f');   /* cursor off */
        ...

Then, the link is:
