I think the workaround for not being able to type an "is unequal to" sign
is to use "<>", as in "24<>25", which would be read as "24 is not equal to 25."



Depends on the language. In the numerous versions of BASIC with which I have had acquaintance, "<>" is used. In C/C++ and java, "!=" is used. In fortran its ".ne." . In perl, as in lisp, there are different versions depending on what you want to compare.
