RSTR_OUT
(Can be used in FASTREXX condition expressions.)
Restores the most recently saved copy of the 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 RSTR_OUT() is invoked twice in succession, then the second invocation restores the same data as the first.
If RSTR_OUT() is invoked without a prior invocation of SAVE_OUT(),
then the output buffer is cleared
. The effect is the same as
executing SET_OLEN(0).
