SAVE_OUT
(Can be used in FASTREXX condition expressions.)
Saves a copy of the current output buffer.
There are no synchronization restrictions. The SAVE_OUT() invocation
that a RSTR_OUT() invocation is reversing
could have occurred
for the current record, or any previously processed record.
There is no stacking of saved output buffers. If SAVE_OUT() is invoked twice in succession, then the data saved by the first invocation is lost.
