I have the following code line:


Here "\" and "/" are the ASC codes 205 and 206.

I get a syntax error:


As I can remember, there was same special in the handling of the special terminal-controlling characters in strings. For example, a reverse ❤ has deleted the screen on print, but it behaved normally in the source code.

Any idea, what could be the reason?

enter image description here

Extension: my tests show it happens with all strings, not only for these. I use vice.

  • I can't reproduce the problem. Can you add a screenshot showing everything you did?

  • The screenshot's line 0 is different from your transcribed line 0.. Sep 17 '17 at 19:50
  • @traal Sorry - for I've thought that it may be caused by some escaping problem, this is what I tried to test. The screenshot contains this test version. However, not this was the reason of the problem (as the accepted answer shows). I can insert it into the post (if the difference can be considered important).

  • @traal I synchronized the post and the screenshot (check the accepted answer - not this was the cause of the problem).

Your problem may be with your READ statement, not the DATA statement. If you have string data, make sure you read into a string variable like so:

10 READ X$

If you try to read string data into a numeric variable you will get a syntax error reported on the DATA line, even though it was the READ that triggered it. So this would give you an error:

0 DATA "A"

The problem is with the flowing line:


String variables in BASIC need to suffixes with a dollar sign $. So all your uses of the variable S should be S$:

2 READS$:X=1024:FORY=1TOLEN(S$):A=ASC(MID$(S$,Y,1)):POKEX,A:X=X-165+A*2:NEXT
