TCL: how to execute program using enviorment PATH variable -

I have found the following line in my script

exec $ :: env (PATH) / program .exe

In my env path variable, I found a directory where I found this executable file. For example: PATH env variable found among other - D: \ my_program \ bin

I have an error:

Error:

  couldn C: \ WINDOWS \ system32; C: \ WINDOWS; C: \ WINDOWS \ System32 \ Wbem; D: \ my_program \ bin; Program ": Do not execute any such file or directory  

Any suggestions on how to make the .exe file using system variables in PATH in TCL?

< P> Thanks

PS OK, when I have created a new ANV variable (PATH1) - without any other path, just a) and set the .exe file path, it seems to work Is PATH (with multiple paths) set to any solution set except D: \ my_program \ bin first?

You should use the Tcl Library function created for this auto_execok .

Try it:

  exec {*} [auto_execok program.exe]  

This automatically searches the path and uses it for exec Creates the correct path.

For example, to start Notepad.exe:

 % auto_e Xecok notepad.exe C: /windows/system32/notepad.exe % Exec {*} [auto_execok notepad.exe]  

To see why {*} is required, take a look. In fact, auto_execok is quite smart and can return the list if necessary, e.g. To run start to run on windows, which requires exec to work properly with the extension.
