Read/write files located in the Working Directory

By default, the working directory is the same as the location of executable files. This directory must have read/write access. First, Lab128 tries to use the directory it started from as a working directory. If this directory doesn't have read/write access, then Lab128 tries to locate %APPDATA%\lab128 directory. If this directory exists, it will be used as a working directory. If it doesn't exist, it will be created with your approval. As alternative, use 'workdir="path" parameter to overwrite the default location.
