RE: SetGT/ReadPE method Exception

Tony,

Try changing your %FOUND to %EOF.  The %Found condition is set off by the SETGT 
operation.  The READPE sets %EOF when it reads the last records not %FOUND.  
Checking %FOUND as you are doing below will fail and use 1 as your sequence 
number because it is using the results of the SETGT operation.  The READPE 
isn't failing, the results just aren't being checked.

This will only happen at the end of the file because the SETGT operation will 
always find a record for all other points in the file and %FOUND will be on.

HTH,

Rick

Well, then I must be running into a different bug. As far as I knew, if the
key value supplied to SETGT is greater than or equal to the highest key
value, %FOUND is not turned on, and the file cursor is not repositioned. If
it were always repositioned, then apparently %FOUND would always be on, in
contradiction to what is in "The Modern RPG VI Language, Third Edition",
page 355. The code I am using below repeats endlessly if the account number
(represented by CI.Family# and CI.Member#) is the highest value in the file.
I have verified the error data and found that the key value it attempts to
replace (Mmseq#) is 1, while the account in question has two memos, sequence
1 and 2.

The only possibility is that
1) The SetGT is failing, due to there being no greater key values
2) The ReadPE is failing, due to the failure of the positioning
3) Sequence 1 is used. The only way sequence 1 would be used (assuming there
is no sequence zero, and I verified this) is this.

Dou Not %Error;

// Find next memo seq# for member
SetGT(E) (CI.Family#:CI.Member#) Mmemo_I;
ReadPE(E) (CI.Family#:CI.Member#) Mmemo_I MI;

If %Found(Mmemo_I);
MO.Mmseq#=MI.Mmseq#+1;
Else;
MO.Mmseq#=1;
EndIf;

Write(E) Mmorec MO;
EndDo;
