To build an indexed file with no secondary key, the following function builds an indexed file with a record length of 266 bytes. There is no secondary key and the primary key begins in the first character of the record and is six characters long

m_FileBuild -t IDX -r 266 -k 1+6 ${DATA}/METAW00.VSAM.CUSTOMER

To build a similar indexed file, with in addition, a non-duplicate secondary key in position 20 with a length of 7 the following function can be used:

m_FileBuild -t IDX -r 266 -k 1+6 -K 20+7 ${DATA}/METAW00.VSAM.CUSTOMER

To build a similar indexed file with a secondary key allowing duplicates in position 20 with a length of 7 the following function can be used:

m_FileBuild -t IDX -r 266 -k 1+6 -K 20+7d ${DATA}/METAW.VSAM.CUSTOMER
