Answer / sathya

yes we can do using sort utility,
//SORTTA EXEC
PGM=SORT
//SYSIN DD *
SORT
FIELDS=COPY
OUTREC FIELDS=(1:5,4096),CONVERT
/*

//SORTIN DD DSN=…,DISP=SHR
//SORTOUT DD DSN=…
//SYSOUT DD
SYSOUT=*
//
The CONVERT control statement is used to convert the
File format from VB to FB.

Answer / ds

Yes. using IEBGENER utility we can copy this. But this is
not advisable until there's a specific requirement.

FB to VB
--------
FB rec length is X
VB rec length should be X+4

VB to FB
--------
VB rec length is X (Length indicated in JCL)
FB rec length is X-4
Note: But here in second case lot disk space will be wasted.

Without the idea of requirement and system design, one
can't say anything.

Thanks, DS.
