Hi, I have a FB CSV file(Delimiter). I need to parse the fields based on delimiter (which is ;). In the output during parse, for numeric fields i do not want to have blanks but leading zeros.

for example:

input file with 2 records

fgghf;1;234;5345;gghhg;ghsad
1;fsad;2312213;565;hghjs;123

output required

fgghf000000100000234000005345bbbgghhgbbghsad
00001bbbfsad02312213000000565bbbhghjs0000123

where b specifies blank

numeric fields can be at any position in input file and hence i need to put a field level criteria during parsing and have output with leading zeros and not blanks.

Here's a DFSORT job that will do what you asked for. I assumed from your example that a non-numeric field would NOT start with 0-9 (e.g. you don't have non-numeric fields like 1abc).

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
fgghf;1;234;5345;gghhg;ghsad
1;fsad;2312213;565;hghjs;123
/*
//SORTOUT DD SYSOUT=*
//SYSIN    DD    *
  OPTION COPY
  INREC IFTHEN=(WHEN=INIT,
    PARSE=(%01=(ENDBEFR=C';',FIXLEN=5),
           %02=(ENDBEFR=C';',FIXLEN=7),
           %03=(ENDBEFR=C';',FIXLEN=8),
           %04=(ENDBEFR=C';',FIXLEN=9),
           %05=(ENDBEFR=C';',FIXLEN=8),
           %06=(FIXLEN=7)),
    BUILD=(%01,%02,%03,%04,%05,%06)),
   IFTHEN=(WHEN=(1,1,FS,EQ,NUM),
      OVERLAY=(1:1,5,UFF,TO=ZD,LENGTH=5),HIT=NEXT),
   IFTHEN=(WHEN=(1,1,FS,NE,NUM),
      OVERLAY=(1:1,5,JFY=(SHIFT=RIGHT)),HIT=NEXT),
   IFTHEN=(WHEN=(6,1,FS,EQ,NUM),
      OVERLAY=(6:6,7,UFF,TO=ZD,LENGTH=7),HIT=NEXT),
   IFTHEN=(WHEN=(6,1,FS,NE,NUM),
      OVERLAY=(6:6,7,JFY=(SHIFT=RIGHT)),HIT=NEXT),
   IFTHEN=(WHEN=(13,1,FS,EQ,NUM),
      OVERLAY=(13:13,8,UFF,TO=ZD,LENGTH=8),HIT=NEXT),
   IFTHEN=(WHEN=(13,1,FS,NE,NUM),
      OVERLAY=(13:13,8,JFY=(SHIFT=RIGHT)),HIT=NEXT),
   IFTHEN=(WHEN=(21,1,FS,EQ,NUM),
      OVERLAY=(21:21,9,UFF,TO=ZD,LENGTH=9),HIT=NEXT),
   IFTHEN=(WHEN=(21,1,FS,NE,NUM),
      OVERLAY=(21:21,9,JFY=(SHIFT=RIGHT)),HIT=NEXT),
   IFTHEN=(WHEN=(30,1,FS,EQ,NUM),
      OVERLAY=(30:30,8,UFF,TO=ZD,LENGTH=8),HIT=NEXT),
   IFTHEN=(WHEN=(30,1,FS,NE,NUM),
      OVERLAY=(30:30,8,JFY=(SHIFT=RIGHT)),HIT=NEXT),
   IFTHEN=(WHEN=(38,1,FS,EQ,NUM),
      OVERLAY=(38:38,7,UFF,TO=ZD,LENGTH=7),HIT=NEXT),
   IFTHEN=(WHEN=(38,1,FS,NE,NUM),
      OVERLAY=(38:38,7,JFY=(SHIFT=RIGHT)))

Thanks a lot frank for the quick reply... I am sorry... a alpha-numeric field can contain or start with numeric integer at any position which has to be with leading blanks.

Please show a better example of input and output with that case and any other cases we have to worry about (for example, values with embedded blanks).

This DFSORT job gave me the output you showed for the new input records.

Code:

//S1    EXEC  PGM=SORT
//SYSOUT    DD  SYSOUT=*
//SORTIN DD *
fg1hf;1;234h;5345;g5h6g;ghsad
1;fsad;a2312213;565;hghjs;123
//SORTOUT DD DSN=...  output file (FB/46)
//SYSIN    DD    *
  OPTION COPY
  INREC IFOUTLEN=46,
   IFTHEN=(WHEN=INIT,
    PARSE=(%01=(ENDBEFR=C';',FIXLEN=6),
           %02=(ENDBEFR=C';',FIXLEN=7),
           %03=(ENDBEFR=C';',FIXLEN=9),
           %04=(ENDBEFR=C';',FIXLEN=9),
           %05=(ENDBEFR=C';',FIXLEN=8),
           %06=(FIXLEN=7)),
    BUILD=(%01,JFY=(SHIFT=RIGHT),
           %02,JFY=(SHIFT=RIGHT),
           %03,JFY=(SHIFT=RIGHT),
           %04,JFY=(SHIFT=RIGHT),
           %05,JFY=(SHIFT=RIGHT),
           %06,JFY=(SHIFT=RIGHT))),
   IFTHEN=(WHEN=INIT,OVERLAY=(51:1,46)),
   IFTHEN=(WHEN=INIT,FINDREP=(STARTPOS=51,INOUT=(C' ',C'0'))),
   IFTHEN=(WHEN=(51,6,FS,EQ,NUM),OVERLAY=(1:51,6),HIT=NEXT),
   IFTHEN=(WHEN=(57,7,FS,EQ,NUM),OVERLAY=(7:57,7),HIT=NEXT),
   IFTHEN=(WHEN=(64,8,FS,EQ,NUM),OVERLAY=(14:64,9),HIT=NEXT),
   IFTHEN=(WHEN=(73,9,FS,EQ,NUM),OVERLAY=(23:73,9),HIT=NEXT),
   IFTHEN=(WHEN=(82,8,FS,EQ,NUM),OVERLAY=(32:82,8),HIT=NEXT),
   IFTHEN=(WHEN=(90,7,FS,EQ,NUM),OVERLAY=(40:90,7))
