[Ari]: I was so frustrated that there is no basic IDE for TCL that I wrote two very basic BATCH files that will get the trick done. You can accomplish the same thing by running a fraction of this code every time in the run command but I figured this might get the job done especially if you are a beginner and just playing around with "Hello World" TCL application. Though this program isn't much it can be really helpful to those newbies like myself. Hard-coded file ====== Rem This program will run any TCL file in the "Programs" folder through a DOS IDE of the ActiveTCL machine Rem Note: Filename must be hard coded into this BATCH file Rem Create command line that will read this file: Rem "C:\...\Programs\" Rem Run it in here: Rem "C:\Tcl\bin\tclsh85.exe" Rem And then wait under you press enter to exit @echo off cls ECHO Program begins here... ECHO "<------------------>" ECHO. ECHO. Rem Set the file name of target TCL file to run Set filename=hello.tcl Rem Target TCL Engine Rem Example: Using ActiveTCL Set engine=c:\Tcl\bin\tclsh85.exe Rem Start folder where TCL file is located Set folderpath=C:\...\Programs\ Rem Run the TCL program via the engine %engine% %folderpath%%filename% ECHO. ECHO. ECHO "<------------------>" ECHO Program ends here... Rem Waiting for user to press a key to quit Pause ====== Passing parameter in RUN or command prompt ====== Rem This program will run any TCL file in the "Programs" folder through a DOS IDE of the ActiveTCL machine Rem Note: Must include filename in the the argument therefore it must be run in a command prompt (or Run) Rem Example: Run the code by going into command prompt and typing "TCLRun.bat hello.TCL" Rem Create command line that will read this file Rem "C:\...\Programs\" Rem Run it in here: Rem "C:\Tcl\bin\tclsh85.exe" Rem And then wait under you press enter to exit @echo off cls ECHO Running: %1 ECHO Program begins here... ECHO "<------------------>" ECHO. ECHO. Rem Target TCL Engine Rem Example: Using ActiveTCL set engine=c:\Tcl\bin\tclsh85.exe Rem Start folder where TCL file is located Set folderpath=C:\...\Programs\ Rem Run the TCL program via the engine %engine% %folderpath%%1 ECHO. ECHO. ECHO "<------------------>" ECHO Program ends here... Rem Waiting for user to press a key to quit Pause ====== Enjoy!
