Seems I need to read up on all the functions in the standard units.
Sorry for wasting everyone's time.<br>
<br>
I do wonder though if it's
worth adding "<Char> in <array of Char>" to SysUtils, since
it's a very convenient and intuitive notation... not just for Chars but
for all basic types, actually.<br>

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