- [ICUAP9.DOC]
- [Harold V. McIntosh, 24 July 1984]
-
- ICUAP9 responds to the SIG/M Disk Editor's column in the June, 1984 issue of
- the ACG/NJ Newsletter, which requested a synthesis of USQ.COM and FIND.COM.
- In the process of trying to meet this challenge, we became aware of some of
- the squeezing and unsqueezing programs in existence, and of the inadequacy
- of our resources both in the library and in our software collection.
-
- Much more than a FIND which will search the SIG/M catalogue volume is needed.
- The whole collection ought to be indexed, according to author, subject matter,
- date of issue, and other things. Not only that, but several years collections
- of Byte magazine, Dr. Dobb's Journal and others need to be indexed. It is
- frustrating to remember that you think you read an article about something
- long ago when you weren't particularly interested in it.
-
- For the moment, we have studied the subject of squeezing and unsqueezing
- sufficiently to think that we have an unsqueezing program which can be
- incorporated into quite a wide variety of other programs, even though it
- is clear that the subject of squeezing files is susceptible of much further
- development. To illustrate the point, we have given both FIND and HELP this
- treatment, and would think of extending it to some editors and assemblers
- if they weren't so proprietary.
-
- This .DOC file is much shorter than our usual custom because the majority
- of the material that it would contain has been incorporated into ICUAP9.HQP.
- That is a squeezed HELP file which illustrates the feasibility of working
- with this class of files. Squeezing usually reduces files to only about
- 67% of their former volume. Even so a system is likely to have quite a few
- HELP files lying about taking up valuable disk space. Thus there is a good
- motive behind any reduction in their volume that can be achieved.
-
- ICUAP9 contains the following programs in various manifestations:
-
- UNSQ The fundamental unsqueezing program
- TYSQ Type squeezed programs, even if .COM files
- FYNDE Search for keywords through a family of files
- HJELP On-line examination of HELP files
-
- All four programs are offered for both the Intel 8080 and the Intel 8086.
- Some have been squeezed; this is redundant but allows the disk to be self-
- contained, because there is a variety of programs present on which each of
- the others can be tested. UNSQ in particular shows how short this program
- can be when it is written in assembly language.
