The following tips, etc for 2068 Programming is from a collection assembled by George Mockridge of TIMELINZ newsletter. These are a little more “advanced” than some that have been published befare.

```
POKE 23730 & 23732 with RAMTOP
```

Resets RAMTOP without destroying variables that were not defined in the program.

```
    1 POKE 23732,0: POKE 23673,0
 9999 PRINT INT ((PEEK 23672+256*PEEK 23673+.5)*100/60/1145+.5)/100
```

GOTO 9999 to find the elapsed time in seconds that a program has been running.

```
FOR N=16384 TO 22527: LET X=PEEK N: POKE N,255-X: NEXT N
```

Inverts the screen display.

```
LET A=1: IF (INT (N/2)*2-N)<>0 THEN LET A=-1
```

Determines if N is even or odd. A=(+1) if EVEN, (-1) if ODD. Normal method of (-1)^N will not work on 2068. Try LET A=COS (N*PI) also works but slower.

```
    1 REM SCREENSAVE
    5 DATA 33,0,64,17,166,222,1,0,27,237,176,201
   10 DATA 33,168,222,17,0,64,1,0,27,237,176,201
   20 FOR A=65300 TO 65323: READ A: POKE I,A: NEXT I
   30 STOP
```

Save a screen to address 57000 and instantly recall it. RAND USR 65300 to UPLOAD and RAND USR 65312 to RECALL.

```
POKE 26692,83
```

Puts line EDIT at top of screen. POKE 26692,75 resets the screen.

```
LOAD ""CODE: RAND USR 33792
```

Try this method to load programs that will not load.
