Software: System
All of the software for the System Form is in the form TyE_FrmSystem.FRM.
The variables which are saved in the initialisation file are in the module TyE_ModIniFile.BAS
Other variables which need to be global are in the file TyE_ModGlobals.BAS.
The code is fairly self explaining by namegiving and comment lines and at the moment of writing this I have no more additional comments.
