Hello Folks,

this is my table of elements (german: Periodensystem der Elemente), which I
wrote for the TI-85. Please use the appended UUENCODED Group-File which
contains all necessary data. I think it should be usefull for scientists, 
students (chemistry,...) and pupils in higher classes.

Make sure you have 16 kByte free RAM before you transfer the group-file!
The program operates temporary with two large matrices. To avoid the 
waste of memory, it stores a single number before exiting in the temporary
matrices. I'm sorry for this solution of memory-managment, but this was the
only way. This results in 2kByte more memory after exiting the pse-program.
But it is necessary you use the EXIT-Key (the same like in menus) to finish
the program.

One additional: if you leave the program whithout typing any key, it leaves
after a duration of three till five minutes. If the duration is to short for
you, please look in the file UPZS, go to the end and change the value in the
test 
If ABSCHALT > 1000
to another value.

If you have problems, hints or something other concerning this program,
please contact me via email:
frank@fb1.fhtw-berlin.de

No question is stupid, I'm glad about every people which (tried?) to use
this program!

Here are only the programs, for those of yours which are interested in
programing. You need the following files if you ungrouped the pse.85g:

CALLUP   85P: support-program, calls sub-programs
OUTDATEN 85P: support-program, prints data
UPZS     85P: support-program, manages the screen
PSE      85P: main-program, launch this!
PSEHELP  85P: support-program, press F1 to see it in action
PSELA    85P: sub-main-program, it displays the Lanthanoids and Actinoids
              (you can use it stand-alone)
PSENGPRG 85P: sub-main-program, it displays the secondary group
              (you can use it stand-alone)
ENWHG    85M: data-matrix: it contains the valency and more (main group)
ENWLA    85M: data-matrix: it contains the valency and more (lanthanoids,...)
ENWNG    85M: data-matrix: it contains the valency and more (second. group)
PSEHG    85M: data-matrix: contains atomic-number and weight (main group)
PSELA    85M: data-matrix: contains atomic-number and weight (lanthanoids,...)
PSENG    85M: data-matrix: contains atomic-number and weight (second. group)
BSVHG    85V: vector for controling the display in the main group
BSVLA    85V: vector for controling the display in the lanthanoid group
BSVNG    85V: vector for controling the display in the secondary group
