For as long as the ADDR-loaded program is in memory, that specific program will be referenced (using its absolute path) even if you change the system PREFIX or current directory after executing the ADDR directive. That is, all subsequent references to any program whose name matches that string will still refer to the ADDR-loaded program.

You can see this in the example below. When the program is executed, ProvideX ADDR-loads "DATECHK", changes directories and executes the ADDR-loaded program even though there is a different current directory and a different program with the same name might exist in that directory.

To unload a program which is ADDR-loaded, either use the DROP directive or execute the START directive.
