Booth,

If RPG program A calls RPG program B, program B does a RETURN without
setting on LR, program A sets on LR, and the user returns to the menu,
program B IS STILL THERE.    And it stays there until you sign off, do a
RCLRSC (not recommended), end program B's activation group (ILE only), call
a program which executes the FREE opcode on program B (not supported in RPG
IV) or call program B again and tell it to turn on LR.

The closing of upstream programs (program A in this case) does not close the
downstream program (program B in this case).
