Early versions of the HLP system drew on the code developed by Roger Noble (Jodrell Bank) which runs on the Alliant machine as part of the OLAF system. Additional guidance came from the MRAO Cambridge HELP system, which runs on Norsk Data computers; listings of this software were kindly supplied by David Titterington. Development of the HLP_COMSTR string-comparison routine was done in collaboration with Paul Rees (Starlink Project). Brian McIlwrath and David Terrett (Starlink Project) wrote the HLIB command procedure and the hlib shell script respectively. The port to Unix was carried out with the help of David Terrett, Paul Rees and Chris Clayton. Further work, concerning use in the ADAM environment, the provision of shared libraries, and the use of the Starlink template makefile was carried out by Alan Chipperfield and Peter Allan (Starlink Project).

The VAX/VMS Help system was an invaluable guide in the development of the specification for the Starlink HLP package.
