Hi.

It seems that I spend too much time programming this little toy :-) ...
Anyway, here is an update to LEMMING version 1.1 .

The changes vs. v 1.0 are :
- sound is generated at the correct time
- align the sixth grob
- speed up
- smother animation
- shorter

It animates a little lemming :-), walking in the status line. It doesn't
change the value of PICT. Once running, you can stop the program by
pressing any key.

If you only want to use LEM, download LEM.ASC into your HP48, execute ASC\->
and store the result into a variable.

To generate LEM, put the listings of LEM.M and LEM.S in the appropriate
files, then invoke the following commandlines at the MesS-DOS prompt:

rplcomp lem.s lem.a
sasm -e -N lem.a
sload -H lem.m

This should generate the file 'LEM' (size 308 bytes, no extension). After
being downloaded to your HP48, 'LEM' should be 307.5 bytes in size with a
checksum of #F3FA. If nothing went wrong, 'LEM' is now executable.

BTW, this program is named 'lemming' because I got the animation sequence
from a game called 'Lemmings'. In the game the actors are called so,
because they're walking straight forward (and fall out of the screen if
you don't stop them) and can be manipulated indirect only.

Have a good time,
8-), Detlef

P.S. If there are any questions feel free to mail me.

Here are the listings:
