RE: Lack of software abstractions

Setting up the J environment (end of step1), and then adding your own scripts 
(end of step2) is probably the easiest way to share your software with someone 
else.  If you are personally installing the software on your own machine or 
someone else's then the installation two step is proabably okay.  However, if 
you are distributing software via the internet or CD then you probably would 
want to have a single install program do both.  I suppose the best way is to 
write an installer that would do everything the J installer does, and then 
simply add your own scripts.  Well, if that's what is needed I guess one might 
as well get used to it...

There are no problems just installing the complete J system and then call
your scripts.
You may of course spend time scaling it down but what is the point.
By having the whole system where your system is running makes life very
easy.

I recently visited a company I did some J work for ca 10 years ago.

They are still running the system unchanged.

The system is based on J calling several programs and shuffling data between
machines using FTP and in some cases calling a small VB routine I made that
sends and receives  files in e-mail.
Only way I did know at the time how to use e-mail from J at the time.

The J scripts start in J runtime called from bat files controlled from a
scheduler.

I described this system in Toronto on the J conference eons ago.

Never had any complaints or even heard much about this for a number of years
now.
Actually thought it had been replaced by something else by now.
There is no J skills at this company whatsoever.
