Wherever SM resides on your system, you need to include its directory in your "set path" statement in your .login file if it's not in one of the standard utility bin directories (I assume Unix). You should also be familiar with the possible output devices available on your system (consult your local SM guru if unsure, or do a "list device" in SM).
Obviously, access to a SM manual would also be an advantage! If you don't have your own hardcopy, you can use the SM Home Page to access the manual and command reference. This is especially true if you are assuming SM is identical to Mongo. SM looks rather Mongo-like, but it is very different. The major difference is that, besides plotting commands, SM also includes a complete scripting achitecture with looping and conditional executions. Some SM commands are the same as in Mongo, but others have quite different syntax. You can look at the scripts to get an idea of what SM can do, even using them as templates for customising to your own needs, but this is no substitute for a real expert or manual. Be warned that SM is rather idiosyncratic, i.e. its syntax requirements are rather picky.
Once you have read in the scripts, you are ready to start Concording. (Or as Oscar Wilde put it, "There is no word in the English language that cannot be verbed.")
If you find SM attractive and discover yourself writing more applications for this package which you think others may find useful, please send me a copy so I can distribute such scripts in future announcements.
