There are several type of variables; Environmental, header and user defined.
Once a scan has been loaded, you may query or modify a header variable.
Environmental variables are ones that can be changed to suit the user and are used to control the behavior of LinuxPops. A few of the environmental variables are internally modified / set by LinuxPops during the course its use,, but most remain untouched save for direct user actions.
NOTE: Variables are being added all the time, so this list may not be up to date.

Users can define their own variable, up to MAX_DYN_VARS, 2048.
All variables, with the exception of characters strings and numerical arrays, can be modified using the assignment function: '='. There are functions that handle string setting. (And we are working on that Array issue...)
