#### 93.2.1 Encountered undefined variable `<x>` in translation

A function was compiled but the type of the variable `x` was not known. This means that the compiled command contains additional code that makes it retain all the flexibility maxima provides in respect to this variable. If `x` isn’t meant as a variable name but just a named option to a command prepending the named option by a single quote (`'`) should resolve this issue.
