If a unit MyUnit declares a resourcestring MyTitle then the name returned will be myunit.mytitle. A resourcestring in the program file will have the name of the program prepended.
The name returned by this function is also the name that is stored in the resourcestring file generated by the compiler.
Strictly speaking, this information isn’t necessary for the functioning of the program, it is provided only as a means to easier translation of strings.
