Re: READE EOF Handling/Repositioning

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."

Hello,

on some occasions, I've come across the following scenario again and again:

I READE a keyed file and eventually hit EOF (because no more records with the given key are available).

The ILE RPG Reference states: "If a READE operation is not successful, you must reposition the file: for example, using a CHAIN, SETGT, or SETLL operation." (aka, the same as with a plain READ).

For a normal READ, I'll do a SETGT to *HIVAL and can READP from there in a backwards order. However, I have no idea how to achieve the same with READPE: I don't know how to tell SETGT to position on the last record before EOF considering a given key value.

Setgt Key Yourfile ;
Readpe Key YourFile ;

will do the magic...
