      - You want to fill up the matrix programmatically without stopping program execution ? Let the flag clear.

      - You want to let the user manually enter the elements while the program waits ? Set the flag.

No incompatibilities nor side effects and functionality is enhanced with minimal effort & cost.

If the flag was left set for some reason, then programs relying on the existing functionality would no longer work, so I think that flag would need to be an auto-clear flag that clears after the next instruction.
