if a dataset is already created with fixed length but after
that i want to change fixed length to variable length then
how is it possible
Answer Posted / varsha
You can convert an FB data set to a VB data set with
OUTFIL's FTOV parameter. Each VB output record has a 4-byte
RDW followed by the corresponding data from the FB input
record, and the length in the RDW is the length of the FB
record plus 4.
The following JCL and DFSORT control statements convert the
bookstore data set records from FB to VB.
//FBVB JOB A92,PROGRAMMER
//S1 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=A123456.SORT.SAMPIN,DISP=SHR
//VBOUT DD DSN=A123456.SORT.VSAMP,DISP=
(NEW,CATLG,DELETE),
// UNIT=3390,SPACE=(CYL,(5,5))
//SYSIN DD *
OPTION COPY
OUTFIL FNAMES=VBOUT,FTOV
/*Because the LRECL of SORT.SAMPIN is 173 bytes, each VB
record in SORT.VSAMP is 177 bytes (the FB record length of
173 plus 4 for the RDW) and SORT.VSAMP is given an LRECL of
177.
