Hi, again. Here is something that may interest you to correct. It’s the READ / DATA statement that makes the data in the list erased of memory somehow after a CLEAR statement or something similar causing an “Out Of Data” error. Here’s an example:
10 'READ/DATA - CMD Ver. 20151204
20 'SAVE "READDATA.BAS",A
30 KEY OFF: CLEAR: CLS
40 X = 17: DIM X$(X)
50 FOR Z = 1 TO X
60 READ X$(Z)
70 PRINT Z, X$(Z)
80 NEXT Z
90 PRINT "LET'S DO IT AGAIN! - Press Any Key"
100 K$ = INKEY$: IF K$ = "" THEN GOTO 100
110 IF K$ = CHR$(27) THEN END ELSE GOTO 30
120 ' DATA
130 DATA "DOG","CAT","SPIDER","FLY","LION","BIRD","TIGER","BEAR","SNAKE"
140 DATA "FISH","SHARK","ANT","ROACH","WHALE","CROCODILE","WORM","BUTTERFLY"
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
OK, thanks! Looks like CLEAR should reset the DATA pointer in addition to the other things it does - will fix this. (Meanwhile, you can work around the bug by adding a RESTORE command to line 30)
