	I have a need for eval to incriment an environment variable.  In
the 1.3 manual it gives and example of how to use eval for this purpose :

eval <env:loop >nil: to=t:qwe{$$} value2=1 op=-?

	My version so far is

eval <env:seq to=t:tmpval value2=1 op=+?

	It returns a 'bad arguments' error.  What's wrong?  I shouldn't
NEED to direct output to nil: (then I wouldn't know that it didn't work!)
and I shouldn't need to include the process number in the to= field. 
What's going on here?  If anyone can mail me a simple program to either
generate Message-Ids to a file with no CRs from the UULIB:seq file and
then incriment this file, or send me a C program to incriment a file
(env:seq) I'll be happy too.

	I'm trying to write a mail-news gateway script to accept all
cases.  I need to add a Path: line to my alt.sys.amiga.uucp mailing list
entry so it doesn't try to mail upstream (don't ask, trust me) and I need
to add a Newsgroups: and Message-Id: line in the case of normal mail.  My
problem is generating the message-id.  I though of using the output from
'date' but that didn't pan out (CR/LFs and spaces).  I need an algorithm
to generate Message-Ids really.
