Bits and Bytes

194 To adjust the delay between repeats on the TS2068 enter POKE 23562,X where X will be on the order of 1 to 5.

195 Some people get confused by the SAVE message “Start tape then press Enter”. On the TS2068 you just need to POKE 26689,38 to start saving immediately.

196 Have you ever had a program that loads on the TS2068 in several parts off of tape that gave you the following trouble? You have the loader program, then a pretty screen presentation, followed by the loading of the main program overprinting the screen and giving an unaesthetic look? To get rid of this problem, do the following in the loader program: POKE 23570,16 and in the main program you can restore by using POKE 23570,6. If you do not restore by the second POKE then PRINT and LIST will be corrupted in your program.

197 If you want your TS2068 INPUT statements to treat caps the same as lower case try changing the mode of the computer. POKE 23658,8 gives uppercase mode, 23658,0 gives lower case mode, 23617,2 gives graphic mode, and 23617,1 gives extended mode.

198 For contrasting color on the TS2068 between ink or paper on the screen try INK 9 or PAPER 9.

199 To get a line 0 in a listing on the TS2068, try POKE 26711,0. To change line 0 to line 1, try POKE 26711,1.

200 On the TS2068 to send all data that is normally headed for the screen to the printer, use OPEN #2. To cancel the redirection, enter CLOSE #2.

201 You can save RAM by some programing tricks. The following three lines produce exactly the same results.

RANDOMIZE USR 100
RANDOMIZE USE VAL "100"
RANDOMIZE USE CODE "а"

The second line saves about 3 bytes and the third line saves two more.

202 Here is a small TS2068 screen saver program.t saves a screen display at address 57000 and recalls it on demand.

1 REM Screen Save Routine
5 Data 33,0,64,17,168,222,1,0,27, 237,176,201
10 Data 33,168,222,17,0,64,1,0,27, 237,176,201
20 FOR I =65300 to 65323: READ A: PORE 1,А: NEXT I
30 STOP SAVE "SCRSAV" CODE 65300,24

Once the code is POKEd you use the following calls to store and recall the screen.

Store: RAND USR 65300
Recall: RAND USR 65312
