Data Chr$(65)

If you run this, it will want to open a blitz3D source file!

I suppose you can't put a command in a data statement. Sadly this kicks my project in the nuts as I need to put Chr$(27) in a string as data statements.

Protean accepts escape character, so I'll see how that goes there. So that's a nother reason why I can't use the Blitz3D IDE.

Yet, incidentally, this doesn't work properly in Blitz3D:

   d$ = d$ + "&#8592;[160" + Chr$(CSI_set_bkgnd_color) + "     "
   d$ = d$ + "&#8592;[161" + Chr$(CSI_set_bkgnd_color) + "      "
   d$ = d$ + "&#8592;[162" + Chr$(CSI_set_bkgnd_color) + "      "
   d$ = d$ + "&#8592;[163" + Chr$(CSI_set_bkgnd_color) + "      "
   d$ = d$ + "&#8592;[164" + Chr$(CSI_set_bkgnd_color) + "      "
   d$ = d$ + "&#8592;[165" + Chr$(CSI_set_bkgnd_color) + "      "
   d$ = d$ + "&#8592;[166" + Chr$(CSI_set_bkgnd_color) + "     "

← is supposed to be the ESC character 27!!! That's a direct copy/paste from Protean!

What is worse is that when I save the bb source file, the ESC character (or the uncanny ←) is translated back into a question mark! I found out while loadling the bb file in notepad.

You can use Chr$(27) directly into your source:

ff = WriteFile("test.bb")

WriteLine ff, "Data " + Chr$(34) + Chr$(27) + "ok" + Chr$(34)

CloseFile ff

If you open the file 'test.bb', and add these lines:

Read x$

For i = 1 To Len(x$)

	Print Asc(Mid$(x$, i, 1))
	
Next

WaitKey()

End

Data "ok"

The first character of x$ is Chr$(27)
So, in order to use your Protean files in the BB IDE, I think you could convert them, replacing every "&#8592" with Chr$(27).

Hmmm, a copy paste of that works! In the Blitz IDE!!! That's perfect b32. I suppose this should be the indirect but working solution, which I'll use from now on.

The idea of making a little test.bb file like this is a good way to circumvent the problem.

Note that if I copy/paste a character coded as chr$(27), it will stay in the source as a character 27. If I type it in with the keyboard (Protean or BlitzIDE), then something weird will happen. I suppose *ALL* the control codes entered by the keyboard are blocked somehow.

Thanks!
