Don't mix variable names

[fbatschi]

Variable names are mixed with uppercase and lowercase/uppercase variants.
There should only be one way to name variables.

Normally you would use uppercase variable names in shell scripts

not in the "local" scope. as this is still "work in progress" not all variable names haven been introspected. The rewrite has a "top down approach". So there are still a lot of variables in the global scope that will not retain there.
