I propose we add a command in DRAW to change environment variables in C subsystem from DRAW, e.g. dsetenv. Then it can be set to update C environment automatically on updates made from Tcl (using Tcl 'trace' functionality), by adding relevant code to DrawDefaults script, e.g.:

proc _update_c_env {envenv var op} {
    global env
    if { $op == "unset" } {
      dsetenv $var
    } else if { $op == "write" } {
      dsetenv $var $env($var)
    }
}
trace add variable env write _update_c_env
trace add variable env unset _update_c_env

Committer: abv Details Diff		 0023197: Draw executable do not detect update of environment variables on Windows.

New DRAW commands dgetenv and dsetenv are added, allowing to query and set environment variables as defined in C subsystem, from Tcl.

On Windows, special handler is armed in DrawDefaults providing automatic update of C environment when Tcl environment (array env) is modified. Note that this is not needed on Linux (Tcl does this internally).

Fixed problem with "array get env" command.

Added comments to _update_c_env proc.		 Affected Issues
