AMPL: A Modeling Language for Mathematical Programming

Determining the Version of AMPL
that You're Running Now

You can look at the current version message by invoking AMPL with the -v command-line switch: 
	% ampl -v
	AMPL Version 20000516
Or, at any point in an AMPL session, you can see the version message by looking at the contents of AMPL's version option, by typing 
	ampl: option version;
	option version 'AMPL Version 20000516\
	';
	ampl:
or 
	ampl: print $version;
	AMPL Version 20000516
		
	ampl:
The 8-digit number represents a date in the form yyyymmdd -- 16 May 2000 in this example. You can compare this date against the dates of the entries in the AMPL change logs and in the writeups of new AMPL features.

If you send the one-line E-mail message "subscribe ampl" to netlib@research.bell-labs.com, then you will receive an e-mail message whenever we update this software. (Updates are made frequently. Send netlib the message "unsubscribe ampl" to turn these notifications back off.)
