global variables

[wilko18]

How so I declare a variable in a module so that it is accessible from everywhere within the program?

I basically want a variable string "query" which I will be assigning varying SQL statements to at various times.

Can I set up my database connections in this way too rather than setting up a connection on every form?

Any variable declared as public or friend in a module is global by definition.
