Business Basic was an integer-only language inspired by COBOL, and contained powerful string-handling functions and the ability to manipulate indexed files very quickly.

In addition to the basic key-to-disk function, the proprietary operating system, called XLOS, supported indexed file operations for on-line transaction processing even with data journaling.

In the case of the HP3000 this was the " IMAGE " shallow-network DBMS and " KSAM " indexed file system, and the entire PowerHouse language reflected its origins.

An indexed file can have multiple alternate indexes ( X ), and in fact, a sequential file may have alternate indexes placed on it so there is no primary index.
15.
An indexed file contains a key, which must be contiguous and may be up to 60 characters long; however, alternate indexes may have three-part keys which are not contiguous with one another.

It's a tool that I've missed for a while, and I've repeatedly checked if google image search didn't offer that some way ( they must already keep hash codes of their indexed files ).
17.
The related locate programs use a database of indexed files obtained through find ( updated at regular intervals, typically by cron job ) to provide a faster method of searching the entire file system for files by name.

Support for indexed files is built into COBOL and PL / I . Other languages with more limited I / O facilities such as C support indexed files through add-on packages in a runtime library such as C-ISAM.

It contained support for multiprogramming, multiple processors, 80 devices, job queues, printer queues, security, indexed file support, and fully installed, it was about 10MB . On the advanced / 36, the number of workstations / printers was increased to 160.
