Heh, okay, I stand corrected. Thanks Michael. Seems I need to read up
on all the functions in the standard units. Sorry for wasting everyone's
I do wonder though if it's worth adding " in " to SysUtils, since it's a
very convenient and intuitive notation... not just for Chars but for all
basic types, actually.

That's because you're defining an array, not a set.
To define it as a set do:
Delimiters = [#9, #10, #12, #13, #26, #32];
Your c in delimiters will work because this is a set.
The FPC source tree is full of such constructs.
The sysutils unit has CharInSet() BTW, if you want to use an array.
