Includes a POKE sequence (LD A,n; LD I,A; RET) and BASIC program to change the I register and display scrambled characters, illustrating how the table is referenced. (2) The PAUSE statement: PAUSE values under 32768 count for n/60 seconds; above 32767 count indefinitely; any key terminates. Maximum self-terminating PAUSE (32767) equals 9.1 minutes.
