Older versions of PHYLIP


PHYLIP has been distributed since October of 1980, when version 1.0 was released. Early versions differed mostly by minor bug fixes, but as time went on more and more changes were included in each release.

Many older versions of PHYLIP are available from our server. These were in Pascal, and what you will find there is the Pascal source code and the documentation files. (At a later date I may also release the compiled executables for some of these versions.)

Extracting the archives

They are in the form of Unix tar archives, which can be un-tar'ed on any Unix server, but putting them in a directory of their own and then issuing the command
   tar xvf phylip17.tar
(or whatever the archive name is).

The tar command will also work in a Command Tool window on Windows 10, and in a Terminal window on Mac OS. These are found, respectively, in the Accessories menu and in the Utilities subfolder in the Applications folder. You might need to omit the "v" switch and use a "-" to designate the switches, as in the command
   tar -xf phylip17.tar

Compiling the programs

You should be able to get the programs to execute by compiling then with Gnu Pascal or with Free Pascal. Some attention may be needed to the RESET and REWRITE statements (and associated ATTACH statements that are needed with them or instead of them). That may include specifying input and output file names in those statements.

More are coming. Version 1.7 is the earliest one that I have. Version 1.0 was released in October, 1980. A reading of the "bugs" file in version 1.7 will show that only a few bug fixes and minor features separate versions 1.0 and 1.7.

These programs are, of course, primitive compared to later programs. They are presented here primarily for their historical interest.


Version 3.5c

Although the official version now being distributed is 3.6, the previous version, 3.5c, was so widely used that it may be useful to continue to have it available here.

Registration of 3.5c
