The easiest way to get a random number is with the XBIOS random
function.  

FUNCTION Random : Long_Integer ;
XBIOS(17) ;

This returns a 24 bit random number.

I usually use an escape sequence to do this.

write(chr(27),'E') ;   { ESCAPE 'E' -- CAPITAL E -- clears the screen }

This information comes out of Atari ST Internals from Abacus
Software, but there is apparently another book available that is a
lot better organized, though the name escapes me...I can find it if
there's any interest.
