Note also that quantifiers are enclosed by parentheses, e.g. (Ex)Rax rather than ExRax, or (Ax)(Fx>Gx) rather than Ax(Fx>Gx). Logical Symbols. Negation, ~.

NOTE: the program lets you drop the outermost parentheses on formulas with a binary main connective, e.g. P>(Q&R) rather than (P>(Q&R)). Since the letter 'v' is used for disjunction, it can't be used as a variable or individual constant. Note also that quantifiers are enclosed by parentheses, e.g. (Ex)Rax rather than ExRax, or (Ax)(Fx>Gx) rather than Ax(Fx>Gx).
