I have a requirement as below.

Input file FB LREC=50
Code:
A1A1,VOL,123.67,,,,
A1A1,VOL,1723.673,JJ,,,
A1A1,,14523.6734,hh,,,

Expected Output:
Code:
A1A1,VOL,123.6700,,,
A1A1,VOL,1723.6730,JJ,,,
A1A1,,14523.6734,hh,,,


So basically, the format is DECIMAL(14,4)/PIC s9(10)V9(4) comp-3. I am trying to reformat this decimal field ( ONLY right portion of it after decimal ('.')to its max limit by adding zeroes as needed).
And later on I will rewrite this field as PD or if you can do it in the same step then thats is good.

I have tried something but that has more hardcoding stuff, so the approach was to take left portion of it (before '.') and multiply by 10000 and add right portion ( after'.') to it.

e.g.
123.67 ---> 123 multiply by 10000
1230000--- add/overlay 6700 .
1236700--- rewrite as PD

So when I read into PIC s9(10)V9(4) comp-3 then I get the right value back.


Thanks in advance.

I tried to do something like this which does add trailing zeroes and then convert that to PD which can be done in Build.
input
Code:
55.2
343.112
23222.11
23.7786


Sort card
Code:
SORT FIELDS=COPY                                         
INREC IFTHEN=(WHEN=INIT,                                 
      PARSE=(%01=(ABSPOS=1,ENDBEFR=C'.',FIXLEN=10),     
             %02=(ENDBEFR=C',',FIXLEN=04)),             
      BUILD=(%01,UFF,EDIT=(TTTTTTTTTT),%02)),           
      IFTHEN=(WHEN=INIT,                                 
      FINDREP=(INOUT=(C' ',C'0'),STARTPOS=11,ENDPOS=15))

Output:
Code:
00000000552000
00000003431120
00000232221100
00000000237786

I think you are basically there.

A couple of things. You don't need the ABSPOS=1. That is the default value for the initial PARSEd field. You need ABSPOS when you want to start the next PARSEd field at a position other than it would naturally be (you want to skip some bytes, or include in the PARSE something you've already PARSEd).

There's also a little thing with ALTSEQ, which removes the need for the FINDREP.

Code:
 SORT FIELDS=COPY
 ALTSEQ   CODE=(40F0)
 INREC IFTHEN=(WHEN=INIT,
      PARSE=(%01=(ENDBEFR=C'.',FIXLEN=10),
             %02=(ENDBEFR=C',',FIXLEN=04)),
      BUILD=(%01,UFF,EDIT=(TTTTTTTTTT),%02,TRAN=ALTSEQ))


That will, for the %02 field, change spaces to zero.

Thanks Bill for ABSPOS=1. and ALTSEQ.
I just coded ABSPOS=1 because I have this type of decimals appeared couple of times at different postions.
