Supermon 64

To get Jim Butterfield's machine language monitor for the Commodore 64 in the January 1983 issue to run properly, it is necessary to change the direct mode command listed on page 164 as POKE 45,232 to POKE 45,235.

Thunderbird

Some additional initialization is required in the Color Computer version of this game, which appeared in the January issue (p. 71). In order to get 1000 points on each new board and 10000 points with a new reset after the second board, you should add these two lines:

2011 TY = 0
3035 HIT = 0

Apple Memory Aid

In the article "Apple Machine Language Memory Aid" in the January issue (p. 160), lines 31, 29, 35, 33, and 51 mentioned in the text should be 310, 290, 350, 330, and 510. In the program listing, line 68 should be deleted.

WAITing On The VIC-20

In the notes in the January 1983 issue (p. 156) on testing VIC-20 joysticks with the WAIT statement, the following changes should be made:

LEFT  WAIT 37137,16,16
DOWN  WAIT 37137,8,8

Atari Simulator

The following changes will allow proper operation of the +, -, *, and / functions in the Atari version of the electronic spreadsheet program Tiny Plan, page 80 of the December 1982 issue.

2310 IF T$ = " + " THEN DA (R3, C3) = DA (R1, C1) + DA (R2, C2)
2320 IF T$ = " - " THEN DA (R3, C3) = DA (R1, C1) - DA (R2, C2)
2330 IF T$ = " * " THEN DA (R3, C3) = DA (R1, C1) * DA (R2, C2)
2340 IF T$ = " / " AND DA (R2, C2) < > 0 THEN DA (R3, C3) = DA (R1, C1) / DA(R2, C2)
2350 IF T$ = " % " THEN DA (R3, C3) = DA (R1, C1) * DA (R2, C2) / 100

VIC Hi-Res Graphics

The following correction will clear up some confusion concerning the article "Understanding VIC High Resolution Graphics" which appeared in the December issue. To make the 8K example (Program 2) load correctly, replace the sentence on page 167 which now reads:

Before typing in or loading this program, type in the following:

with these corrected instructions:

Type in Program 2 and then SAVE it. Next, type in the following three POKE commands and then LOAD your hi-res program.

CalCalc

For those in the age bracket 40-50 who felt left out when attempting to use this program from the December 1982 issue (p. 84), the line below should be added to both the Microsoft and Atari versions.

785 IFAGE > = 40 AND AGE < = 50 THEN CPD = 3008 : IF SX THEN CPD = 2162

Atari Lister

In the program on page 191 of the January 1983 issue, the GOTO 32710 in lines 32715 and 32725 should be changed to GOTO 32705.
