I am developing an application using some nontrivial DSP algorithms. To develop those algorithms, I've created a special application as a more ideal test environment, which is not the real user interface itself. I'd like to use TCL for the user interface of the real application, but obviously I'd like to avoid changing the code that does move over to the real application any more than necessary. Do any of you have any words of wisdom, or know of any useful books, MacTutor/Tech articles, or CompuServe threads, or whatever, that discuss any "gotchas" that could come about from dropping large chunks of nonTCL code into a TCL environment? As for my level of TCL understanding and background, I've read the TCL documentation, but I've never actually written any code for it. Thanks folks!
