The best thing you can do is tinker. At least, that was the best way for me to learn. I’m better with hands-on type things. A few tips:
– The testing tool in Cloverleaf is your best friend. Save a test message as a txt file, and use the TPS testing tool. Send it to the proc hcitpstestshowbydisp. The result will show you both the output and disposition of the message, as well as any echoes that you put in your script.
– Speaking of the testing tool, reverse engineering your current tps scripts will help you understand the function of a tps script. Play with them, comment things out, echo variables to see what they are. Just make sure not to overwrite any functional scripts that are currently in use in your environment. Obviously, that would be a very bad thing…
– Google is also your friend. Prefix your search with “tcl” and you will typically find the exact thing you need. Ideas would be “tcl get item from list” or “tcl search for string.”
– The Intermediate Cloverleaf class will help you a lot, but my opinion is that you should be fairly competent with tcl before you enroll. If you already have that foundation, you will learn a lot of cool tricks. If you don’t have a decent understanding of tcl, you may lose a lot of the concepts as soon as you leave the training.
