Just a note to add some information to kempers reply. There are numerous helpers available now to aid players in games all of which have their own unique designs, pros, and cons. However all helpers are not created equal. Some of the helpers are designed to be a little more flexible than others. Some come with their own scripting languages added so that you may write your own customs scripts and macros for your own personal needs as the situation warrants. Examples would be swath, attac, j-twat etc. Twxproxy acts as a go between server for your helper, telnet app, and the tradewars server and also has scripts to compliment most any kind of playing style. Zoc is not an actual tradewars helper but has evolved as one of the more popular telnet apps where you can either d/l numerous scripts from various tw sites or write your own scripts. One of the most popular setups is using ZOC through the twxproxy server and can make a very deadly combination. I prefer ZOC because of its easily definable macro buttons, automacro buttons, and Fkey button designations to make an almost endless array of macro combinations for on the fly editing either for combat or repetitive needs where a prewritten script may not quite fit the need.
The best advice for your clients would be to try all the different helpers and pick the one that best fits their playing style and needs. Some players might actually prefer to use different helpers for different applications. Some may like swaths graphical map but prefer to use attac for the script designs so forth so on. All the helpers I’ve seen usually have a trial period where you may use it for 30 days or so then purchase a license to unlock all the extended features. J-twat is one that is a open source free application you can use and learn how to modify to fit your own needs.
Also have your clients ask specific questions in any forum eis for example and I’m sure other players will be happy to report their personal reviews of the different helpers and their functionality.
Long winded but hope it helps
