Using env variables in tcl script

[Soumen]

Hi,

If I do following in tclsh prompt, it works;

%set i [array names env PATH]
%echo $env($i)

But if I wrap it in a.tcl, source it in tclsh prompt and call test, it
gives me following error:

can't read "env": no such variable

----------- a.tcl -----------------
proc test {} {
set i [array names env PATH]
echo $env($i)
}
--------------------------------------

%source a.tcl
%test
can't read "env": no such variable
%

Please let me know how to resolve this.

Regards,
~ Soumen

Please post to a TCL group or forum like comp.lang.tcl. This group is
for standard C. You might also try comp.programming.

Would you like us to diagnose your car's timing problem as well?

This has nothing to do with C - why should we be expected to know
anything about it?

There appears to be a comp.lang.tcl group - why not ask there?

No, sorry, you are wrong. See, tcl is written in C, therefore this is
on topic in a C group.

See, ultimately, we all know that "tcl" is just a wrapper around the
underlying C runtime. For example, the error message that the OP
mentions - that actually comes from C.

Interesting. That might work, as well.
