However, HASP was developed in the field and not in an official IBM development lab. My remembrance is that there were four program product types. Type I was produced by IBM developers, a critical component of the system, and fully supported. Type 2 was produced by IBM developers, an application, and fully supported. Type 3 was developed in the field by IBM employees who were not in a development lab and then contributed to IBM for general distribution to other IBM customers, but not supported (in general, except for a few like HASP). Type 4 was developed in the field by IBM customers' employees and then contributed to IBM for general distribution to other IBM customers. I think that IMS started out as a type 4, being originally developed at an aircraft manufacturer in the Los Angeles area by personnel working directly for that aircraft company .

HASP was not an FDP. HASP was a [so-called] "Type III" program, but with the unusual characteristic that it carried "Service Classification A." That meant that HASP was, effectively, supported at the same level as OS/360 or OS/VS2. In actual practice, of course, HASP was supported much better than either OS/360 or OS/VS2 Release 1. Type III programs were "submitted" (for distribution by PID -- which we came to know as "Packaged In Darkness" because of the many errors made by PID) by one or more IBM employees . They were "programs of general interest submitted for unrestricted distribution." A very limited number of Type III programs were fully and formally supported (Service Classification A) by IBM. Such programs performed "functions which [were] fundamental to the operation and maintenance of the user's system." Examples of other Type III Programs were APL\360 and "Attached Support Processor" (i.e., ASP). ASP was program number 360A-CX-15X HASP-I Version 2 was program number 360D-05.1.007 HASP-II Version 3 was program number 360D-05.1.014 HASP-II Version 4 was program number 370H-TX-001 HASP Version JES2 was an SCP component of OS/VS2 Release 2 For a trip down memory lane, browse the figures, pictures, and lists of programs, etc. in this 1970 SRL publication: http://www.textfiles.com/bitsavers/pdf/ibm/360/GC20-1619-8_Catalog_of_pgms.p df -- WB =
