The VTOC should start right after the volume label. The first record in the VTOC should be the FMT4 (Format-4) DSCB record. The second record in the VTOC should be the FMT5 (Format-5) DSCB record. Here is a pointer to the layout of the Format-4 DSCB: http://publibz.boulder.ibm.com/cgi- bin/bookmgr/BOOKS/dgt2s330/1.1.1.5?
