RE: (E) Extender and %Error on WRITE

["Wilt, Charles" <CWilt@xxxxxxxxxxxx>]

The service program looks good, but in the module you're using %found()
which is not set by the READPE.

The operations that set %FOUND are: 
  v File operations: 
        - "CHAIN (Random Retrieval from a File)" on page 573 
        - "DELETE (Delete Record)" on page 595 
        - "SETGT (Set Greater Than)" on page 738 
        - "SETLL (Set Lower Limit)" on page 742

Subject: Re: (E) Extender and %Error on WRITE


The module source:
-------------------------------
Dou Not %Error;

// Find next memo seq# for member
SetGT(E) (Family:Member) MmoRec;
ReadPE(E) (Family:Member) MmoRec Mm;

If %Found(Mmemo);
Mmo.Mmseq#=Mm.Mmseq#+1;
Else;
Mmo.Mmseq#=1;
EndIf;

Write(E) Mmorec Mmo;
EndDo;
--------------------------

The MMEMO file is uniquely keyed by account number and sequence number
(MMSEQ#). I have since written a dedicated service program that handles
this
operation a bit differently:

---------------------------
Dou Not %Error;
SetGT(E) (Family:Member) MmoRec;
ReadPE(E) (Family:Member) MmoRec M;

If %EOF(CMmemo);
Mo.Mmseq#=1;
Else;
Mo.Mmseq#=M.Mmseq#+1;
EndIf;

Write(E) MmoRec Mo;
EndDo;
--------------------------------------
But at the time the first program went haywire, the above service
program
wasn't being used by the program. There are no triggers on the file. I
don't
have detailed data about when the error happened (I am not currently
analyzing based on the status code, just using %ERROR).

Thanks for looking at this.
