The data entry was either described in several tables that specified the format of the input record with optional automatic data validation procedures or the indexed file operations were programmed in a special COBOL dialect with IDX and SEQ file support.

The initial COBOL compiler supported the ANSI 68 specification and supported the ENTER SYMBOLIC syntax to allow inline assembler coding, but lacked support for RELATIVE and INDEXED file support; these were later added into the ANSI 74 version of the compiler, which was released in 1982.

Of course part of the IPL was typically keysorting the indexed files and if the machine had been shut down without a " keysort " ( performed part of the P S ( or STOP SYSTEM ) then depending on the number of indexed files ( and their sizes ) it could take upwards of an hour to come back up.
