Re: READE EOF Handling/Repositioning

[Brian Parkins <goodprophet.bp@xxxxxxxxx>]

PS. Avoid using *LOVAL / *HIVAL for these operations. Use *START or *END 
as required. From the manual:

"Figurative constants can also be used to position the file. However, 
there are some situations where using *LOVAL or *HIVAL does not position 
the file exactly at the first or last record in the file; it is better 
to use *START and *END if you want to position to the first or last 
record in the file."
