TclForth Inner Interpreter (Engine)

TclForth provides a simple solution for the threading of Forth code and the appropriate inner interpreter: We pass the job to Tcl.

words are Tcl procs that call Forth procs. The Forth proc is defined by calls to Forth (colon and code) procs.

The inner interpreter of Tcl is also the inner interpreter of Forth.
