Declare the variable in the interface section of a unit, then add
that unit's name to the uses clause of the unit you want to access it
from.

put it in the main form for your application and be sure all other forms
have the main unit in a uses clause under the IMPLEMENTATION section (not
the program command where all the other uses clauses are).

If you have lots of this you can create a unit with only one purpose and that is to have global variables.
Just put them under the public part and include this unit in all units that need to use it.
