These files are for use by PostScript interpreters which support
an interactive executive.

Using the file operator on %statementedit accumulates input in
a temporary buffer, parsing editing control chars, until a statement
has been read.  A statement is (quoting from the new Redbook) "one or
more lines terminated by a newline that together form one or more
complete PostScript language tokens, with no opening brackets
( {, (, <, or <~ ) left unmatched."  When the statement has been read,
file returns.

%lineedit is like %statementedit except that it returns after a line
has been read, regardless of whether that line is a complete statement.

> and what other special files are available?

These are all of the special files that are described by the new Redbook.

See Section 3.8.3, Special Files, pp. 78-80 of the PostScript Language
Reference Manual, Second Edition.

Information about these files is also in the original Redbook.
