hi everyone,

i'm working in TCL/tk8.0 in unix. i want to implement Threads in TCL
scripts. are there any TCL commands for implementing Threads. i learn
that using some functions in C we can create threads for TCL Script.
but my project must only have TCL scripts and no C code.

can anyone help me in this regard.

thanks,
Prabhu

Tcl/Tk 8.0 is rather ancient. There is a good thread extension for more
recent versions of Tcl (especially 8.4.x) which allows script level
access to threads.

A. All true.
B. "I'm working in TCL/tk8.0 ..." concerns me.
I don't know whether that means you are
committed to the specific 8.0 sources (in
which case we need to talk about old copies
of extensions from the AOLserver gang), or
are simply reporting the depth of your
current experience.
C. I have an even greater concern that "I
want to implement threads" might actually
be "code" for, "I am on a project with
concurrency requirements, and don't realize
that threading is only one of several con-
currency mechanisms Tcl offers, and likely
not the one best for my situation."

Tcl/Tk 8.0 is old, you should upgrade to 8.4.x. There is a very good Thread
package for 8.4, but I don't remember how stable it was with 8.0.

Also, do you really need Threads -- they are *very* rarely needed in Tcl.
Most things are better handled with event driven programing in Tcl.

Why don't you describe what you want to do a little more -- the problem not
your proposed solution?

The first version of Tcl that was thread-safe in its released state
was Tcl 8.1.
