In Tridora Pascal, this syntax also works because `[ 'y', 'n' ]` will not be treated as a set literal, but as an array literal.
The _in_ operator also works for linear arrays, so the _if_ statement will have the same result.
The _in_ operator also works for linear arrays, so the above _if_ statement will have the same result.
Note that the array _in_ operator will be more inefficient for larger ranges (i.e. `'A'..'z'`), but more efficient for sparse sets (i.e. `'A','z'`).

- _read_/_write_ do ASCII conversion on scalar variables, records and arrays are processed as binary
- enums and booleans are treated as integers
- _readln_/_writeln_ operate as expected, that is, they perform _read_/_write_ and then wait for/write a newline sequence
- other file operations available are _eof_, _eoln_ and _seek_
- other file operations available are _eof_, _eoln_, _seek_ and _filepos_
- for error handling there is a function _IOResult_
- terminating the program without calling _close_ on open files will lose data
