| stringEqual s1 s2 | Function |
stringEqual compares Lpp String s1 to Lpp String
s2 and returns t if they are the same length and all
characters of s1 are the same characters of s2.
Otherwise nil is returned. For example:
stringEqual(L("foo"), L("Foo")) => nil
stringEqual(L("foo"), L("foo")) => t
| stringEQUAL s1 s2 | Function |
stringEQUAL is the same as stringEqual except that
character case is ignored. For example
stringEQUAL(L("foo"), L("Foo")) => t
