I am using a different version of TCL - where did you get your TCL from?

Did you check if TCL is in your PATH?
IMO, the simplest solution would be to reinstall TCL on your Windows - it takes you only some minutes.
First uninstall old TCL and install new. Anyway, the version 8.5 is already old. The proper version for windows is [url

This is where I got TCL from

https://www.activestate.com/activetcl/downloads.

I need a 32bit version because I will later install tcom which did not work on 64bit. So I have the choice between 8.6.6.8607 and 8.5.18.0. It turns out that 8.6.6.8607 does not come with teacup (which I need for downloading packets like tcom).

So after a lot of installing and uninstalling several different versions I am left with 8.5.18.0. that "should" have what I need but the problem described in my question persists. Even the newest version of Tcl 8.6.7.0 raises the problem.

I added the paths C:\Tcl\bin AND C:\ActiveTcl\bin (different path for the other version) both to my user variables and my system variables. This path is also where wish.exe is located so TCL and wish "should" be traceable.

What about the "[info commands button]" - any ideas where that piece of code looks to get a value?

Thnx

Somehow I managed to solve this. There was an init file the tcl-script referred to and in which paths had to be customized. So now tcl knows where to find wish.

Thanks for your effort.

as described here

https://www.tcl.tk/man/tcl8.0/TclCmd/info.htm#M8

info commands <pattern> return list of command specified by the pattern
In your case the command button is not found so the list is empty and you get the error message.

It could have several causes:

1. I don't understand why you have 2 paths for tcl, i.e. C:\Tcl\bin and C:\ActiveTcl\bin ?
Maybe you mix 2 versions, one installed properly and other not.
I have ActiveTcl installed by default in the C:\ActiveTcl directory and have in the PATH only C:\ActiveTcl\bin

2. It seems that your script runs in tclsh and not in wish:
When I take this piece of code
inesw.tcl

Code:

if {[info commands button]==""} {
  puts "Wish not used"
} else {
  pack [button .hello -text "Wish is available" -command { exit }]
}

and run it on command line in tclsh I get similar message like you:

Code:

c:\>tclsh inesw.tcl
Wish not used

But when I run it on command line in wish

Code:

c:\>wish inesw.tcl

then the button with the message appears:

When I simply double click on the script inesw.tcl, it will be automatically opened with wish and the button appears (like on the screenshot but without command line window).

It seems that something gone wrong with your Tcl installation on Windows ...
Didn't you changed file association in your windows, so that the files with the extension *.tcl should be opened by tclsh ?

I haven't looked but it is strange that the latest versions do not have teacup. It is normally in the same directory as tclsh and wish.

It seems, that teacup was dropped from newer Tcl versions:

Now I checked teacup on 2 Windows machines at my work. On both ActiveTcl 8.6. is installed.
On the older machine I found Win32 version and teacup is present in the Tcl\bin directory and works.
On the newer machine I found x64 version and teacup is not available.
So really, who wants to use teacup needs Win32 version.

I have been switching back and forth between different versions (one at a time). So I added the path for each version and left it there even after uninstalling that version.

Yes, I set *.tcl to be opened by tclsh by default. This is still the case now (after solving the wish-error). I will have to meditate on this a little more.

Thanks for your help.
