Strange behavior of tab character
« on: November 30, 2025, 05:27:09 pm »
Why does writeln sometimes display the tab character (ascii #9) in a string with a little circle, instead of performing a character gap?

Probably you output it with stdout in RAW mode.

This happens in one of my apps, but not in others. What setting affects this behavior?

canvas.Textout Does not support a TAB, you must emulate it,

WriteStr, Write and WriteLn should work, however.

If those are not working then yes, something is amidst !

You don't give much information, but units like CRT or VIDEO (used anywhere in the program!) might have such effect.

For some reason, I had unnecessarily included Crt in the uses clause of the unit where writeln was exhibiting this strange behavior with tab. I'm under Windows. Removing the inclusion solved the problem. Thanks Marcov!
