- The LEAVE opcode of the RPG, within a nesting level, the "LEAVE causes

from the manual suggests "In nested loops, LEAVE causes control to
transfer 'outwards' by one level only", but it may intend to imply
nested Do-groups vs _loops_ because the LEAVE can be used in a
non-iterative DO\ENDDO according to the same poster; i.e. the earlier
comment "In RPG it is [allowed to LEAVE a non-iterative Do-group]".

RPG's DO group is always a loop. If you don't specify the number of iterations, it defaults to 1.

I don't think there's anything in the DO documentation that suggests that there is a non-iterative DO-group.

Unlike CL, RPG doesn't need DO and ENDDO to delimit the statements for an IF or an ELSE, so DO is only needed for looping.
