Returning from a Main Procedure

A return from a main procedure causes the following to occur:

• If it is a cycle-main procedure, and LR is on, then global files are closed and other resources are freed.
• The procedure's call stack entry is removed from the call stack.
• If the procedure was called by the program entry procedure, then that program entry procedure is also removed from the call stack.

A cycle-main procedure returns control to the calling procedure in one of the following ways:

• With a normal end
• With an abnormal end
• Without an end.

A description of the ways to return from a called cycle-main procedure follows.

For a detailed description of where the LR, H1 through H9, and RT indicators are tested in the RPG program cycle, see the section on the RPG program cycle in the IBM Rational Development Studio for i: ILE RPG Reference.
