- Here are some commonly asked questions about Texx.
-
- Q: What is Texx based on?
- A: Texx is based on the REXX language. REXX has been around in the IBM
- mainframe arena for some time. REXX is currently available in the
- Unix, MS-DOS, OS/2 and Amiga platforms. There are more versions
- appearing.
-
- Q: What do I need to run Texx?
- A: You need a minimum of System 7. Any CPU and memory configuration
- that comfortably runs System 7 and applications should be sufficient.
-
- Q: I have non-Apple Event aware applications, can I still use Texx?
- A: Yes. With the exception of the four required and the the DO SCRIPT
- Apple Events, all the supported Apple Events apply to the Finder. The
- majority of the scripting will be directed to the Finder. As an example, you
- could send the Finder an Apple Event to open a document and the Finder
- will send a non-Apple Event application the command to open the
- document.
-
- Q: I need to do more useful things that the basic Apple Events don't do, can I?
- A: Yes and no. If you have an application that has its own scripting facilities,
- use them, have Texx send it a DO SCRIPT Apple Event. If not, wait until
- Texx supports the Object Model.
-
- Q: I don't always want the Profile.exec or Shutdown.exec to execute, how can
- I prevent them from executing?
- A: New with Texx version 0.3, you can hold down the shift key and Texx will
- bypass executing Profile.exec or Shutdown.exec. Please be aware that if
- you press the shift key too soon on startup, Texx will not launch. The rule
- that I use is wait for the Texx application name to appear in the menu bar
- before I press the shift key.
-
- Q: I'd like to use Texx, however, it locks up my system and forces me to reboot,
- is there a fix for this problem?
- A: Yes. First, it doesn't really lock up your system. You probably sent the Finder
- an Apple Event specifying a file that doesn't exist. What happens is that the
- Finder does not send back a reply to Texx. So Texx just sits there and waits
- until the operation finishes or a time-out occurs. The system is not locked up,
- it just appears to be. If you wait for the time-out, everything will resume.
- New with Texx version 0.3, the COMMAND-. ( COMMAND-PERIOD ), will cancel the
- wait and return things back to normal. Now, instead of forcing a reboot, try
- the COMMAND-., you might need to bring Texx to the foreground.
-
- Q: Is Texx a better product than AppleScript or Frontier?
- A: Well, certainly, AppleScript and Frontier are more capable than Texx 0.3.
- However, I hope that Texx will catch up to them in the near future. I've gotten
- both positive and negative comments, mostly positive. I've also heard positive
- and negative comments about the other two. Clearly it is a matter of taste.
- I haven't worked with AppleScript or Frontier, so I can't comment. I can say
- that REXX users are highly biased toward REXX, and in environments where REXX
- is used, REXX is indispensible. Another benefit is that REXX exists on several
- different platforms, the other two don't.
-
- Q: How would you describe the REXX language?
- A: The REXX language is one of the simplest languages to learn. It is structured
- like C and Pascal without the "typing" of either language. Some people use
- REXX as a macro processor-like tool to automate repetitive tasks. Others use
- REXX as their application development language. In either case, the language
- extremely flexible and powerful. A programmer will find REXX very easy to
- learn and at the same time very powerful. A non-programmer will find REXX
- very flexible and forgiving with a short learning curve. Regardless of the
- technical expertise of the user, REXX will satisfy anyone. Even though Texx
- is not yet a full implementation of REXX, Texx will give a taste of REXX and
- allow you to sample what REXX is about.
