Actually, program described printer files can take either alpha or
numeric overflow indicators (external files do require numeric
indicators).

The main difference is that numeric indicators must be set off
manually, while the alpha indicators are set off by the RPG cycle. 
If you're not using the RPG cycle, then you need to set off the alpha
indicator manually as well.

I seem to remember another potential problem with alpha indicators
when not using the RPG cycle; something like the overflow indicator
not getting set back on because the detail output part of the cycle
was never being executed (until the end of the program).  It's been a
_very_ long time since I tried this, though, so it may not be the
case.
