Convert VB file to FB and Convert FB file to VB using SORT

The below JCL copies the VB file to FB file.

//STEP01 EXEC PGM=SORT
//SORTIN DD DSN=INPUTVBFILE,DISP=SHR
//SORTOUT DD DSN=OUTPUTFBFILE,DISP=SHR
//*
//SORTWK01 DD SPACE=(CYL,10),UNIT=SYSDA
//SYSOUT DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=(5,76,CH,A)
OUTFIL FNAMES=SORTOUT,VTOF,BUILD=(5,76)
/*

The INPUTVBFILE is a VB file with record length 80.
The OUTPUTFFBFILE is a FB file of record length 76.
Before executing the JCL it is assumed that both the SORTIN and SORTOUT datasets exists.
SORT FIELDS=(5,76,CH,A) sorts the input VB file.
VTOF will handle copying the VB file to FB file.
It is essential to give BUILD or OUTREC parameter when VTOF parameter is used.

Below JCL will Convert FB file to VB

//STEP01 EXEC PGM=SORT
//SORTIN DD DSN=INPUTFBFILE,DISP=SHR
//SORTOF01 DD DSN=OUTPUTVBFILE,
// DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,
// DCB=(LRECL=80,RECFM=VB,BLKSIZE=84),
// SPACE=(TRK,(3000,2000),RLSE)
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL FNAMES=SORTOF01,FTOV

It is not essential to give BUILD or OUTREC parameter when FTOV parameter is used.
