RE: RPG400-L Digest, Vol 5, Issue 676

Alan,

What I am trying to do is this:

We are trying to keep track of all changes that are made in our master
files.  Currently we are journaling these files (Data Mirror).  I create
a file of all changes to a file using the DSPJRN *OUTFILE cmd.  I then
create a file using the DSPFFD *OUTFILE cmd on the file the user wants
to see what changes were made.  I use the DSPFFD file to find out how to
substring the data that came from the DSPJRN cmd to create a "|"
delimited file.  The problem comes when some of the data from the DSPJRN
are packed.  This is because one of the files we are journaling has a
field that is packed.

I am hoping that I don't have to do what Scott and Bob suggest and that
would be to use the MI instruction.  if that is the only way to
accomplish this then that's what I will do, but wondering if there is
another way.  

I want to keep this a generic as possible so anyone can select a file
and a date/time range and get a delimited file of the changes that were
made.

Thanks for all the suggestions so far.

Curt

Curt - I believe some more information is required.
Does the packed data start and end in the same place for each character
string?
If so, can you supply a breakdown of the initial character string?
If not, how is the packed data delineated from the non-packed data?

Does this work?

   eval  fieldp = %dec(%subst(longfield: 12: 10)
(where 12 & 10 are the starting position and length)?

and, could you eval your result field with %editc(fieldp: 'Z') ?

Use the _LBCPYNV MI builtin to convert the packed data to zoned decimal.

Curt,

Try this: 
H BNDDIR('XTOOLS/XTOOLS') 
 /copy xtools/qcpysrc,numtochar

 eval  %char(numToNum(%subst(myData:3:4) : 'P' : 7 : 2))


This requires RPG xTools, however.
If you don't have xTools, look up the LBCPYNV MI instruction, which is
what I
use under the covers.

Subject: Moving Packed Data

I am working in RPG IV.  I am trying to substringing out of a character
field, packed data.  I am trying to put this packed data back into
another character field, but I don't want it packed, I want to see the
actual value.  How do I accomplish this?  I tried substringing into a
character field and then moved that into a signed field, but that does
not work.  I get a decimal data error.  I don't want to create a data
structure either cause the format of the initial character field could
change.

Any suggestions?
