Hi all,
Can you please guide how to concatenate 3 fixed block files of different LRECL to a fixed block file.
i.e.
INPUT:----
FILE1--FB--LRECL:100
FILE2--FB--LRECL:200
FILE3--FB--LRECL:300
Output:----
FILE4--FB--LRECL:300 |

The below SYNCTOOL job should work for your requirement.
| Code: |
//STEP1 EXEC PGM=SYNCTOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DISP=SHR, Input file-1, FB/100
//IN2 DD DISP=SHR, Input file-2, FB/200
//IN3 DD DISP=SHR, Input file-3, FB/300
//T1 DD DSN=&&T1,DISP=(MOD,PASS),DCB=LRECL=300
//OUT DD DISP=SHR, Output file , FB/300
//TOOLIN DD *
COPY FROM(IN1) TO(T1) USING(CTL1)
COPY FROM(IN2) TO(T1) USING(CTL1)
COPY FROM(IN3) TO(T1)
COPY FROM(T1) TO(OUT)
//CTL1CNTL DD *
INREC OVERLAY=(300:X)

It doesn't look like it......

Concatenating Input Data Sets
SyncSort must determine one set of DCB characteristics to use for reading all data sets in
the concatenation. The following rules apply to the DCB characteristics:
• When the first data set is fixed-length (RECFM=F, FB, FBS), all subsequent data sets
must be fixed-length and have the same LRECL. |
Try looking at the JOIN, different inputs can have different record lengths and formats. |
