Try this 4K ROM listing - do not put any spaces in the lines with REM:
Code: Select all
1 RAMDOMISE
2 GO TO 50
10 PRINT "I WIN"
15 REM
20 PRINT "NO, I WIN"
25 REM
30 PRINT "WINNING HERE"
35 REM
40 PRINT "ERR... I THINK I AM THE WINNER"
45 STOP
50 GO TO RND(4)*10
A practical use for this - I think - would be:
Code: Select all
10 IF A={condition to ignore next line} THEN REM
20 PRINT "SOMETHING"
Regards,
Shaun.

I found this by accident:
Code: Select all
1 PRINT "HELLO ZX80 FANZ";
2 POKE 16421,38
[EDIT] The POKE is wrong, I've worked it out. Please see attached demo (32 x 24 text in BASIC).
This seems to remove the message at the bottom of the screen. I was using EightyOne for this.
Thanks,
Shaun.
