RE: Aborted dump -- RPG400-L

You get the error 'Error occurred while retrieving variable data.  Dump
terminated.' when the program/module is compiled with OPTIMIZE(*FULL).

Subject: Aborted dump


I have a program that is now blowing up.

RNX0100 - Length or start position is out of range for the string 
operation. 
CPF9999 - Function check. RNX0100 unmonitored by EXCLEIACT at statement 
0000001286,
  instruction X'0000'. 
RNQ0100 - Length or start position is out of range for the string 
operation (C G D 
  F). 

When I take the D option all I see are the indicator variables:
...
Internal Indicators: 
LR '0'    MR '0'    RT '0'    1P '0' 
Error occurred while retrieving variable data.  Dump terminated.

>From the compile:
Compiler options . . . . . . . . :   *XREF      *GEN       *NOSECLVL 
*SHOWCPY 
                                     *EXPDDS    *EXT       *NOSHOWSKP 
*NOSRCSTMT
                                     *DEBUGIO   *EVENTF

1286 C                   dow       ExceptionId=*blanks and 
1287 C                             %subst(DataRead:1:DataLen)<>'*SHUTDOWN'

I think I figured out the error on 1286.  The read of the data queue 
containing DataRead, DataLen, etc has not occurred.  Why this ever worked 
is beyond me.  I am changing that to:
      // changed the following from a dow to a dou because DataLen was 
equal to
      // zero and that is a problem.  Seemed to work earlier, but a 
recompile
      // and attempt to run it always ended in an RNX0100 message.  Odd.
      // Using the DOU means it will only check it at end of the loop 
time.  At
      // that time the field should be initialized.  Well hopefully if it 
ever finds
      // an exception id then it doesn't bother to check the rest of the 
dou
      // statement.  Because at that point we could have problems.  Hmm, 
hows about
      // me initializing DataLen?  You got a problem with that?
     C/free
       DataRead=' ';
       DataLen=1;
      /end-free
     C                   dou       ExceptionId<>*blanks or
     C                             %subst(DataRead:1:DataLen)='*SHUTDOWN'

However, why did the dump abort?
