J.3.12 Release MD-1.1

A description of the major differences between the existing IAS version and the newly released MD version 1.1 (summer 1989):

$\bullet$ Improved user interface: suntools menu interface at help=8. The sophistication of the user interface is determined at compile time through a number of compile switches in getparam.c

$\bullet$ Standardized usage of some standard interactive facilities using setparam instead of and with help of getparam.

$\bullet$ Installation through Makefiles is more flexible. The installation and various administrative utilities are more streamlined to make porting to non-SUN's easier.

$\bullet$ Aarseth's straight N-body code - as published in BT87 is in nbody0 and an Ahmad-Cohen version in nbody2 (this last one has not been tested out well enough) These programs have a NEMO interface, which also handles some Fortran-C interface questions.

$\bullet$ filestruct_old is now obscure: all of Piet's clib programs have been converted (snaplist, snapenter, snapdist, mkplummer)

$\bullet$ various new yapp's, the $NEMO/src/nemo/yapp directory has been cleaned up and documentation has been updated.

$\bullet$ bodytrans saving: the program bodytrans can be tested and also save files (-DSAVE_OBJ compile switch) - same for library routines.

$\bullet$ snapplot and movies work better together; snapplotedit.

$\bullet$ potcode

$\bullet$ ds, image display on image(5) or fits(5) files.

$\bullet$ fortran interface

$\bullet$ GRAVSIM added to nemo/src tree

$\bullet$ lars/treecode has been added, but needs a good recursive fortran compiler. NEMO interfaces built in. Not been able to test well - Does not work on Suns..

$\bullet$ The NEMO startup file is now called NEMORC.

$\bullet$ This expanded manual.
