Variables and Types - There is no information about the types for the executable ASCII file.
StringByteLength - There is information for the executable ASCII file

The expected text:

There is no such information required.

Where do you expect that text?
Current PureBasic versions do always generate executables in Unicode mode.
The comment in the help of StringByteLength

If omitted, the mode of the executable (unicode or ascii) is used.

is obsolete and should be removed.

Yup.

- Removed: ASCII mode for internal PureBasic string representation, PureBasic is now unicode only.

All functions (PeekS, PokeS, ReadFile, CreateFile, OpenFile, CompareMemoryString, MemoryStringLength, etc.) specify which format is used by default. Do the same for StringByteLength(). I don't think there should even be any questions here, everything is obvious.

What you wrote was not obvious and not clearly understandable.

Removed that.

But I agree, that a "(Standard)" should be placed behind one of the 3 options / constants in the description. But I don't know myself... Unicode or Utf8?
