I almost forgot to mention that you do not need to concatenate path strings the way you are, ie.:
Application.Path & "/tmp.gambas"
Application.Path & "/" & exeName

You can simply use the path concatenation operator '&/' which will add the slash if it is needed and won't if it is not.
For example: Application.Path &/ "tmp.gambas", or Application.Path &/ exeName
