Common errors

A common error is to use double quotes rather than single quotes around a character literal, as in myChar $""x",$ yielding a compiler error.

Similarly, a common error is to forget the quotes around a character literal, as in myChar $=x,$ usually yielding a compiler error $($unless $x$ is also a declared variable, then perhaps yielding a logic error$).$
