String manupulation in JCL

Postby nikesh_rai » Fri Mar 08, 2013 4:30 pm

Hi,

I have a file with inputs like:

BIT-STRD-INFO
BIT-SEQ-NBR
TEL-LINE-NBR

and needs to process the input and output should be:

B-S-I
B-S-N
T-L-N


Can wo do this using Sort JCL or better to go with REXX...
Please suggest..

Thanks
Nikesh

If you use PARSE with "-" to delimit the fields, you can then
  BUILD=(%00,2:C'-',%01,4:C'-',%03,6:75X)


That is for 80-byte records. If you want five bytes for your LRECL, then you might be able to use IFOUTLEN or another BUILD of 1,5.

Thanks Billy,

But the problem is variable string length, like

RATE-STRUC-ST-DT
PBE-INSTNC
BILG-ELMT-CAT-CODE


Which shoud be processed as

R-S-S-D
P-I
B-E-C-C
Thanks

did You care to read the <sort> manuals or search the forum for examples of the PARSE clause ???

Well, you need enough PARSEd fields for your maximum number of elements, and only to put the "-" if the "next" PARSEd field is not equal to spaces.

I have already checked with PARSE and some manuals as well, but was not able to resolve my problem.

You will need a two stage approach ...
PARSE to split the single tokens
<BUILD> to extract the first char

Something like this, which is for "four-element" names, so note what happened to the last test data.

//STEP0100 EXEC PGM=SORT
//SYSOUT   DD SYSOUT=*
//SORTOUT  DD SYSOUT=*
//SYSIN    DD *
  OPTION COPY
  INREC IFTHEN=(WHEN=INIT,
                PARSE=(%00=(ENDBEFR=C'-',FIXLEN=1),
                       %01=(ENDBEFR=C'-',FIXLEN=1),
                       %02=(ENDBEFR=C'-',FIXLEN=1),
                       %03=(ENDBEFR=C'-',FIXLEN=1))),
        IFTHEN=(WHEN=INIT,
                BUILD=(%00,C'-',%01,C'-',%02,C'-',%03)),
        IFTHEN=(WHEN=(1,1,CH,EQ,C' '),
                OVERLAY=(2:79X)),
        IFTHEN=(WHEN=(3,1,CH,EQ,C' '),
                OVERLAY=(2:79X)),
        IFTHEN=(WHEN=(5,1,CH,EQ,C' '),
                OVERLAY=(4:77X)),
        IFTHEN=(WHEN=(7,1,CH,EQ,C' '),
                OVERLAY=(6:75X))
                                                       
//SORTIN   DD *
RATE-STRUC-ST-DT
PBE-INSTNC
BILG-ELMT-CAT-CODE
                                                       
TEST
TEST-TOST-TIST
1-2-3-4-5


Gives:

R-S-S-D
P-I   
B-E-C-C
       
T     
T-T-T 
1-2-3-4

BillyBoyo,

You can simplify the job using the parm "STARTAT" instead of "ENDBEFR" on PARSE and then pick the values. Makes it quite easy. :D Something like this

//STEP0100 EXEC PGM=SORT                               
//SYSOUT   DD SYSOUT=*                                 
//SORTIN   DD *                                       
RATE-STRUC-ST-DT                                       
PBE-INSTNC                                             
BILG-ELMT-CAT-CODE                                     
                                                       
TEST                                                   
TEST-TOST-TIST                                         
1-2-3-4-5                                             
//SORTOUT  DD SYSOUT=*                                 
//SYSIN    DD *                                       
  OPTION COPY                                         
  INREC PARSE=(%01=(ABSPOS=2,STARTAT=C'-',FIXLEN=2),   
               %02=(STARTAT=C'-',FIXLEN=2),           
               %03=(STARTAT=C'-',FIXLEN=2)),           
  BUILD=(1,1,%01,%02,%03)                             
//*


The output
R-S-S-D 
P-I     
B-E-C-C 
         
T       
T-T-T   
1-2-3-4 


You can use an OMIT condition to remove all spaces records.
