ZX Destroyer (2:4)
The author suggests the following changes and clarifications:
Figure 6:
1 REM: 6th line down, last character is U. Last line, change last F to E.
2 REM: 1st line, change C (5th character) to A; change 2 (4th character from right) to 1.
30 REM: 1st line, change 4 (5th character) to 5.
Figure 7:
Line 90: changee 243529 to 243473; 488940 to 488758; 612608 to 612426.
Line 110: change 733561 to 733408.
Figure 8:
Do not enter lines 10-35.
Author’s note: I have a SLOW converter from MicroAce which apparently has a different character sync. This causes small lines on some characters on some computers. POKE 16547,1 might help. Some problems with the alien’s laser can be corrected for those who have the program already entered by: POKE 16748,13; POKE 16764,149; POKE 16779,140.
Just for Fun (2:5, p. 20)
The first character of the following carry-over lines was lost. Add at the beginning of the carry-over:
Zap: Line 40: a period.
Catch 25: Line 120: a comma.
Block Transfers (2:5)
p. 71, Figure 2:
Line 230: Delete.
Line 260: Add a ; at the end.
