i have two PS files and i want to compare them to find out the uncommon record between them using rexx.

can any one suggest me the rexx code for the same????

Thanks a loot in advance.

With all of the other tools that do this better (SUPERC or SORT), why REXX? Anyway, if you do have to use REXX, what's the process (i.e. the algorithm) you plan on using?

i have two PS files :
FIle A: LRECL(42) FB

CL12009030000005100000000015281717D0000R01
CL12009030000005100000000025281741G0000R01
CL12009030000009400000000010435662D0511J00
CL12009030000011600000000015794376A0000R01
CL12009030000011600000000026823751{0000R01

similarly it contains multiple records

FIle B: LRECL(205) FB

I want to compare these two files and to find out the uncommon record between them ..

one more thing the key starts from 28th position and the length of the key is 8

Hello,

To repeat - this is not a job for rexx.

Your sort product is a better choice to do what you want to do.

hi you can even file -aid for the same to compare 2 ps files and get uncommon recs.

in the control card u give the keys to be compared i have done this some 3 years back so i couldnt recall.
//MP07U194 EXEC PGM=FILEAID,REGION=6M
//STEPLIB DD DISP=SHR,DSN=SYS1.FILEAID.LOAD
//SYSPRINT DD SYSOUT=&SYSOT
//SYSLIST DD SYSOUT=&SYSOT,DCB=(LRECL=183,BLKSIZE=1830)
//*
//DD01 DD DSN=file1
//DD01C DD DSN=file2
//* DUPLICATES ON HISTORY
//*
//DD01CO1 DD DSN=file3,DISP=(,CATLG),
// DCB=(RECFM=FB,LRECL=90,BLKSIZE=27000),
// SPACE=(27000,(15000,100),RLSE),UNIT=DISK
//*
//DD01CP DD DSN=(control card1 where u will put compare options),DISP=SHR
//*
//SYSIN DD DSN=(controlcard2),DISP=SHR
//*

u can give in control card the which is generated by the fileaid as below (u need to give fields positons and all that)
